Well first off I'd maybe try to quit yelling at your few good friends, and ruining relationships you have with them..is there a specific reason you're doing that? Also do you get college loans...is the job nessisary? If you don't 'need' the job maybe it would be a good idea to let it go and focus on college....seems like maybe you're just putting too much on your plate and its stressing you out which is effecting your grades, and relationships.

No ones forcing you to join clubs or get involved on campus...if you feel those would be good things to do...take it slow, and maybe try out going to like one club see how that goes and go from there.
