I am 26 and i do have anxiety. I did therapy for it, I had depressed periods. We all do have our own battles in our lives who others won't understand. I also felt bad about myself, I would want to to many things and yet I am distracted or I feel tired and that prevents me. One thing I learned about myself is that I cringe a lot when I see someone I know on street and have to greet them because it is polite(probably because I am sometimes insecure about myself) Recently I actually want to greet them because I want to be polite not because it is social convention. i don't even do that to feel more selfconfident I just do because it is a good thing. It feels right and I feel like I have bit nicer connection with others.

Besides that, as Sadhguru said(you tube guru, funny man but smart and kind) "depression is business". You and I are the same pretty much, we are born here on planet Earth, live for some time and we try to do good stuff.

So don't overthink, don't ask youself deep questions, you are fine, many of us would like to hang out with you. Be yourself, we are on the same boat. :)
