((Cyran0)),
Welcome! I'm sorry you are in so much pain.
I can understand the feeling of wanting to just jump in after all your meticulous research. I remember feeling exactly that way when I began therapy--not because I researched but because I felt like I was going to explode!
I hope you can set aside some of that fear and get some rest. You might want to begin journaling -- it has helped me to write down my fears, dreams, etc. It may help you to clarify thinking (and ease the pain) while you wait for the first appointment.
Good luck and let us know how it goes!
