Life without singing???

So ever since the car accident, I have been having trouble singing. At first I couldn't because my head hurt. Then I thought I just didn't feel like it, because of the pain I was feeling. After being in situations where I needed to sing, I now know that I cannot sing without feeling dizzy or having my jaw ache (and thereby causing my neck, shoulder, and/or other muscles hurting). I am going to physical therapy, and I specialist next week. My physical therapist wants me to go to a TMJ specialist, but I need to go to Dr Shepard first and most likely he'll send me to the TMJ specialist as he and Dr Romney talk after. I have a friend from high school who doesn't sing so much any more as she got TMJ from a car accident and can't. I am afraid that I will never be able to sing like I have always been use to, ever again. I can't imagine my life without being able to sing as much and as often as I want. That isn't me. I don't want to have to get used to that life. I am really scared that I may never be able to sing fully ever again, and I don't know what to do. What if I can't fix this??????? I feel very lost! Music is my life! Dec 3, OK so on Dec 19 I get a lavage (kinda like surgery but not really), so here's to hoping it fixes the problem!!!!
