I have gone through the same thing this past year and finally decided to see a therapist, good news is that the depersonalization (unreal feeling) is the worst stage of anxiety. So you can only go up from here. I am also on zoloft and buspar. I've been on zoloft for a couple months now, and it does take a while to kick in but just bear with it. If you want to know what to expect on the meds and see the success rate, just google zoloft reviews. Everyone is different you will have to try different dosages to see which fits you best, it's a trial and error. I'm at 100 mgs right now and feeling about 70% which is better than I was before. You really have to be patient with the illness and go easy on yourself, also really consider seeing a therapist. Best of luck
