what kind of BS advice is "stop caring" ?
we live in a society where we are FORCED to care and criticize ourselves because if we're happy with who we are, we won't buy a majority of what they are selling.
social anxiety is much harder than "lol stop caring u pansy"
all i can suggest OP is slowly build yourself up to it. Maybe try and find someone online who has made progress in dealing with their own social anxiety. You may be able to bond and help each other.
Sometimes you have to remind yourself that we judge ourselves the harshest because we are conditioned to do so. You may have to just bite the bullet, go into the social situation, and try to convince yourself that it is all just you, that they probably really truly do not care.
As for a job, I'd go around to the various businesses in your area, ask if they are hiring. dress your best. if you're looking to get a job thats more corporate, make a resume, look up companies that are hiring, and send it in.
the hard part will be the interviews though. I have yet to get a job because i get so nervous, I probably end up looking like a huge idiot to them.
and for making friends, I second the idea of joining a club. Do you go to a relatively big college, OP?
also when you say college, are you meaning it in the US sense, or the UK sense?
