Psychological Tests and Quizzes

My advice is that if you don't want to see a professional right now, maybe find someone you trust, someone who doesn't know you, and talk with them about the possibility. Like a local nurse or doctor, and maybe print out a couple 'tests' that you can do and discuss your answers with them. Then again, I don't know your situation so take some warning with my response...
