Feeling worthless and unimportant....

I know how you feel, man. It sucks when you feel like your friends have left you behind or that you're saying the right things when trying to meet new people but it doesn't work. I personally think you should focus more on you cause all of this stuff has most likely taken a shot at you confidence. And of course until you feel less alone, like you said, you always have your friends around here.

Keep strong and keep looking. If you give up, your future soulmates will never get to meet you. I have friends; just not friends I can be myself around. I'm not really alone, but it's lonely at the same time. So I know how you feel in a different way.
