Funny, because being single for me does not make me alone.
I don't get why everyone is so obsessed with finding someone to make them whole. Especially at your age. You have no idea how much your world is going to change over the next ten years. So i recommend that you focus on yourself first and foremost. That's what I did. I focused on my relationships with friends and family and worked on making myself a better person. I started volunteering and being friendly. So far it's worked pretty well for me. I have a lot of people that i can count on and i've never been in a more solid place in my life. I don't care if i ever find a partner. I mean, if i do that would be great and i would welcome it with open arms, but i am perfectly happy being single knowing i put my best foot forward, i help others, i'm kind to people and there are amazing people around me.
Best of luck and i hope you find your happiness.
