Combining lots of pills can actually worsen your condition and yes, doctors make such mistakes all the time. If you've been prescribed more than 2 or 3 pills, then better consult one more specialist.
As for my disorders, together with SA and mild agoraphobia, it is possible that I also have Asperger's. I discussed it with my psy two days ago, I don't fit all the criteria, but he said it's possible to have mild AS, considering the fact I am in my twenties now and most of the symptoms are gone. Happily, it appears I don't have any prominent personality disorders, which is good, considering I am enough of an eccentric without them.
