I have been on a few different anti-depressants. Sertraline (Zoloft) helped my anxiety the most. I took it for about 5 months last year before switching to another anti-depressant (unrelated to anxiety), but it helped reduce my anxiety massively. I've just tried it again after being on a few that made my anxiety worse, and after only 2 weeks of taking it, the main side-effect I have had is an increase in anxiety. So I guess it's hit and miss, but I hear a lot of stories about how SSRIs (anti-depressants) help anxiety as well as depression and other mental health disorders. There are also other options such as tablets you take as and when you need them, I've never been on these, and there are also benzodiazapene but I'm not sure about this. I don't know much about the last two options. SSRIs are definitely worth a shot though in my opinion.
