Hi ladies! I also suffer from this fear/feeling of passing out, especially in public and while driving. I feel for you and your situation. I'm (finally) in my last semester of college and going to class is really difficult for me. Being in an unfamiliar place with people I don't know really bothers my anxiety. I've found that if I tell people about my condition and make them aware that, "Oh, hey, I have really bad anxiety and I might pass out," I'm able to deal with it a little better because I feel safer knowing that I'm not alone with it. I'm also frustrated with my situation because I wasn't always this way and I know that I am capable of doing things on my own.
I'm not necessarily a fan of medication, but currently take an array of pills for my anxiety. I'm finding that the more I take, the worse I feel. On top of my anxiety, I'm also a recovering alcoholic (going on 10 months sober; 2 years in recovery) so my psychiatrist won't prescribe me any narcotics (Benzos, etc.). I recently started taking Seroquel at night to help me sleep. I've been on it for about a month and really like it so far; weird dreams though. I've found that taking Celexa (which is an SSRI) with my Buspar makes me angry, irritable and I also snap at people. On days that I don't take it, I'm not as angry. Vistaril (Hydroxyzine) helps when I feel a panic attack coming on. So if you don't want to continue with the Ativan, which I was also on for about a year, I would suggest Vistaril.
I would agree that medication is totally a bandaid and not a cure at all. I don't want to live like this, but for the meantime, it helps. And I would also suggest talking to other people about it, not necessarily just a professional. You'd be surprised at how many people have this problem.
Hope this was helpful! Good luck with your move! Oh and you should watch Long Island Medium lol; she has anxiety too.
