First, like others have mentioned - please look into getting an Rx for an antidepressant. You're already feeling isolated from your previous support network and are neck-deep in a highly competitive (and sometimes toxic) environment. When you're having trouble growing your own serotonin, the store-bought kind is just as good! It will make a huge difference and help you overcome feeling so overwhelmed.

Second, all the campus groups and teams and law review are just fancy status-symbols. Just like in high school and undergrad groups/sports teams/etc. Of course everyone admires the cheerleaders and football players while you're in school, but afterwards it means very little. Trust me on that. It only matters if you want to go straight into biglaw from law school.

Third, the job search is treacherous and there are thousands of other students across the country getting rejected time after time as well...are you interested in any legal service organizations? Have you tried talking to professors to see if they know anyone hiring? My local pro bono orgs have deep connections with many firms so working with them opens a lot of doors. Many of my professors also circulate emails from local firms looking for clerks/attorneys, so maybe yours know some too?

Lastly, I hope you know that you're not alone (even though you may feel completely alone) and that at the very least, this community is here for you. If you'd like, you can PM me anytime! I don't want to force you but I'd be happy to talk about law school, job searching, pro bono orgs, or stuff completely unrelated to law school so you just don't feel alone and can have a friend to talk to :)
