If you are considering to take medication for your depression, be aware of a few things. It's common for people who take antidepression meds to feel even more down for the first period. I myself had Paroxetine, and did experience this.
Also, watch out with alcohol.
When you're depressed, it's you who got into this and it's you who can get out. Nobody but yourself can get up, and take action. That's one of the most valuable things in life to me, taking charge of your own life. Start easy, be satisfied with the smaller things you do in order to feel better again. Keep moving, maintain or rebuild social contacts. Exercise, run, paint, or do something that brings satisfaction.
During the time i was depressed, i thought i couldn't sink further. And yet i slipped a little more each day. Until i realised that enough is enough.
It's been a year since then, i still need to stay focused to keep up the good work. But i tell you, the time i thought i'd hit rock bottom, is a time that i never want to forget. It's valuable, adds something to yourself. How else could you define the good from the bad in your life?
Good luck, be well. You'll get there.
