well, pretty sure we've all been through this type of thing in the past/present so they're might be a few of us that'd supply reasonable answers.
Just gain a little confidence in yourself and stop beating yourself up about the things you supposedly lack.
Trying doing something productive and open to people some can be understanding.
I've suffered from depression from the 7th grade all the way to the end of 9th grade I know what it feels like. People may believe your hard to approach or something relevant to that since that's the problem I use to have before my life turned upside down
