Anxiety starting to control my life.

In middle school/high school I was very outspoken. I was the funny girl who covered up her feelings with laughter. I was somewhat shy, but always pushed through it. My anxiety started getting increasingly worse around 19/20. I'd have a hard time hanging out with friends, and starting overthinking a lot. A lot of self doubt and issues. Now at 22 I find it a big task to even leave my house, I don't have any friends. I worry almost constantly, my mind is always in overdrive. Last year I was in a car wreck while I was driving, since then my anxiety has made driving such a nerve wracking thing. I overthink every detail. Plan out what roads I'll take, and am constantly paranoid that something is wrong with my car. I don't trust myself behind the wheel anymore, and before my wreck it was never a problem. I ask family to take me places if I'm not familiar with the roads. I hate talking on the phone, I stutter and sweat talking to people I'm not fully comfortable with. I've been on 4 different SSRI's (Prozac, Celexa, Cymbalta, Effexor) and didn't ever see a difference. They also killed my sex life which is depressing in itself. I was also given an allergy medication for my panic attacks which only made me fall asleep. I gave up on that doctor who I felt wasn't listening to me and started buying benzodiazepines off the street, and felt incredibly guilty for it. I ran out and decided to stop taking them 3 days ago, although they do help. Doctors don't want to prescribe them because others abuse them. I'm just at a loss for how to handle everything I guess, and don't know where to turn.
