Stimulants that stimulate the release of dopamine can have either negative or positive effects, depending on the drug. Too much caffeine can make you more anxious and exacerbate your social anxiety whereas amphetamines can give you more energy but at the same time, act as sort of a traffic cop for your thoughts. That's why they work for ADHD patients.

I'd suggest trying other methods first, though. Once you get on some of those drugs, it's hard to get off. I know someone who has been on one drug or another for over 30 years.

Try meditation and living your life mindfully to reduce your anxiety. It can actually change your brain chemistry naturally. Try out a meditation group. A lot of beautiful women go to those groups, so there's an additional benefit.
