Well several things..... (this is long)
One, a psychologist is just a person. They don't have any magical powers or special abilities that anyone else has or doesn't have. That might sound silly but it is important to not let the perceived authority of others intimidate you needlessly. Psychology isn't math, it's a shit ton of guess work and no one will ever know your mind better than you yourself are able to.
If you think your therapist is a moron or an overly religious idiot don't be afraid to find a new one. Just like there are plenty of bad dentists and good ones, bad doctors and good ones, bad RJ posters and good ones, so too with therapists. Probably even more so as therapy often requires a different touch with each different patient as treatment is so personal. Most doctors learn one way and apply that one way to all situations.
If you don't like your therapist or feel you aren't getting anywhere after a few visits (or even 1 if it goes badly) find a new one. Don't waste time with someone who isn't reaching you. If they aren't reaching you, chances are they just aren't into working all that hard....it's an easy job to become lazy at. Imagine if your job required only talking and a few mental exercises, how easy would it be to just be bad at it?
Two, quit drinking. You have identified you have a problem with alcohol. Alcohol is fattening, it's a depressant, it can be addictive, it costs money and clearly it is not making you happy. It's also an exercise in discipline to quit drinking, everyone everywhere can benefit from being more disciplined.
Quit drinking immediately and resolve yourself not to drink again until your personal and professional situations are better. You can drink again in the future, tell yourself, so it doesn't seem like you are giving up something you enjoy but just taking a little break. It may be a shitty few weeks while your body gets used to not having any alcohol...chew gum, masturbate more, go for walks or jogs....find something to do instead of drinking.I'm reacting to everything in my life and at work very badly
Do you mean things are stressing you out? Or do you mean you are reacting over emotionally to people in your life?
For in the moment type stuff such as snapping at coworkers or friends etc.... try counting to 5 or 10 in your head before you respond to any negative situation. Sounds silly i am sure but a few extra seconds to think can really help remind yourself that becoming angry doesn't help anything and often leads to bad choices. How many movies are there about boxers trying to make the other boxer angry so he does dumb stuff in the ring?? It works in fighting because human brains react badly to the chemicals released when we are angry, our decision making abilities are lessened. Anyone who has played poker angry knows this.
For overall "my life sucks" stuff, you need to find some sort of meaning or philosophy that allows you to maintain perspective. Some people do this with religion (which is foolish!) and some people do it with family or relationships and some people do it with goals or projects. I mean everyone does it with a combination of the three, even if you don't think you have a life philosophy that sort of is one! lol
The point is to give yourself the ability to step outside of yourself and look at things as not being as important as they feel.
Take the death of a beloved pet. Something that happened to me last year. My dog was so much to me and had been for a long time. That might sound silly to you, but regardless, that dog was more important to me than any person ever in my life past or present, any 3 people, any 10. I could say for quite certain, i would gladly trade the lives of everyone i have ever met to bring my dog back. Perhaps an unhealthy view no doubt, but i am just trying to point out that the death of my dog was a very big personal deal to me.
In order to get past it without too much mental anguish or risk of personal injury, i had to think of reasons to be ok with the situation. I needed to create a narrative in my head why i was going to be ok and why this situation wasn't going to be as painful as i feared.
The first step was allowing myself to understand and accept that it didn't need to be painful in order to have meaning. We all have this pre-set way we feel asthough we should react when something "bad" happens or is happening.....but you can challenge that. Feelings don't matter as much as actions. My dog was dying, i needed to ACT in order to end his suffering but i didn't need to feel any particular way about it. I needed to ACT after he died, continue to eat and sleep and live and interact with the world, but i didn't need to feel any particular way about it.
You need to allow yourself the ability to find a reason or reasons to take control of your own mind and create your own narrative about what is happening to you and in the world. Your world.
This is easy for some and very hard for others. It all depends on how willing your are to embrace new ideas and new views that lead you feeling in more control. That is what therapy is really, it is giving yourself the tools and ability to see things differently. If you go to therapy convinced that you needn't change anything and that all your thoughts are exactly the way they should be and there is no reason to change anything because the world is the way it is and you are the way you are....then of course you are right! If you go to therapy with an open mind seeking to learn and believe that it can help you in some way, then of course you are right then too!
As for your work out issues....you are aging. Sorry. I am 35 and i can tell you if i worked out like i did at 30 my arms would fall off and that would be that. Recovery becomes more and more important as we age. Proper diet, proper warm ups, proper form, proper rest, massage, stretching all become more and more important. Daily things, like using the computer, improper posture, sleeping on the correct mattress etc. etc. all take their tolls too.
At 30 i could sit at the computer all day and not feel anything. If i tried the same today, my shoulders would fall off.
Who knows why you are getting injured more. But that fact it is happening suggest that you need to change a few things or atleast keep more attention to proper functioning and best practices to maintain that functioning.
As for my personal experiences with therapy, yes the first time was scary. I had never seen a therapist before i didn't know what to expect. I have had many bad therapists and psychiatrists and one ok one, and one good one.
I am not sure what you can expect to get out of the experience. I do recommend going. I also recommend joining a mental health forum of some kind and interacting with people who have experience dealing with these types of issues. Crazy people, such as myself, often have had to look deeply into the root of their own suffering and mental short comings in order to survive. When you are a certain level of fucked up, you need to develop an ability to reprogram yourself to a degree or else you'll end up dead or in jail or locked up.
So even if you feel your problems aren't that bad, that's good. It might make you feel good to hear or read about people that are much more fucked up than you, i can promise you'll find a few that can relate and offer good advice.
Treat this as any other problem. If your car had problems you'd google shit and maybe go to a car forum and get advice from someone who had similar issues. Then you'd go to a mechanic. Why should this be any different? Get a few second opinions and go from there.
