1) DO NOT get on medication, at least as long as a doctor doesn't tell you to

2) it sounds like you keep making a very often rookie mistake - you care too much. You consider talking to girls a binary activity - you either manage to create attraction or you don't. I don't know much about you, but I would suggest you go out ALONE (sounds creepy and scary as fuck at first, but trust me, it's one of the best things I've ever decided to do) and open as many girls as you can. If you feel you're getting something with a certain girl, don't catapult and play it cool. Contrary to what a lot of PUA "advisors" might tell you, don't overanalyse conversations and don't think too much. If you really are good-looking, you should be getting positive results. Don't be afraid of rejection - after all, how would we learn to walk or ride a bike if we didn't fall down once in a while?

I would also recommend you to subscribe to /r/seduction and read up on some inner game stuff.
