What do you suggest if i'm so shy and worried about every little thing?

Talk psychotherapy: For a good start, i'd recommend some sessions with a clinical psychologist to evaluate your issues. From there you'll either hear referral for meds and definition of work to do in talk sessions w/ homework or or maybe not need the meds. Think of it as coaching. Many people don't learn how to handle things very well. It's not easy, but many can learn if they want to and try. Good luck!
