It won't be as bad as you think. You will be asked questions to see how severe. I was once even handed a paper with questions to fill out. You won't be treated like you're crazy or making it up. They will want to know how long it's been going on, how it is affecting your life, if you've ever been treated for it before, are you suicidal, do you self harm, does it run in your family? Answer honestly. Depending on these answers you will probably be started on medication and refered to a psychologist.

I also have trouble answering questions or just talking in general, but I guess I got my point across. My doctor actually made me feel a lot better about myself. I always work things up to be much worse than they are.

Good luck!
