Please Help!!

So i've been suffering from what my doctors have diagnosed as TMJ for almost 6 years now and it's gotten to the point where medical intervention is needed.

A little background on my TMJ. All this pain started after my car accident my junior year in high school. I was t-boned from the left side but it did not cause any injuries to me or the other party. At first there was no problem, but slowly i began developing headaches and neck/shoulder pains which was caused by me grinding and clenching my jaw (my parents could hear me when i was sleeping all the way in there room). Later in the year my jaw hurt so bad i went to go see a dentist who supposedly specialized in TMJ. He told me that i grind my teeth so bad basically all of my teeth were worn down and leveled. He made me a splint which i wore for about a year until i lost it. It helped but it didn't fix anything. As soon as i reached college i noticed that it had gotten worse and now (here is where my problem is) i move my jaw around constantly!!! What i mean by this is that, all day because i feel tension on the left side of my jaw i pop my jaw left and right, open and closed until it felt better (usually i do it about 3 or 4 time till it "feels" better).

i have severe clicking and popping when i do this and it causes pain in my ear in my eyes and my neck and back.

Sometimes it gets so severe (moving my jaw around) that people constantly ask me why i do "that" with my jaw. I don't know why i do it for the longest time i thought it was natural because my jaw was misaligned but everyone i talked to who has tmj or knows someone who does, doesn't seem to do what i do. I feel like i'm the only TMJ patient who has this particular problem.

just to illustrate the severity i move my jaw at least a couple hundred times a day.

Finally it got to the point where i was in so much pain i went to go see an orthodontist (my dentist suggested this). My orthodontist said i have TMJ and that it may have something to do with my severe under bite. So to his suggestion i am undergoing a series of treatments to help with this. In conjunction with an oral surgeon and my orthodontist they said that i should get braces and then after a year have jaw surgery to correct my bite. Also they said that because of the way all 4 of my wisdom teeth grew in it was causing tension in my jaw, so they decided to remove them while i have my jaw surgery.

Now it's nearing the time to get my surgery and slowly i feel less and less confident that this will help. Maybe it's because i'm nervous or something but i've been so stressed about it i'm in the worst pain of my life!! I feel like i have a disability because people are constantly asking me why i move my jaw around.

Does anyone have a similar problem? Have they had any success with a similar series of treatment? Anyone just have any good advice as to how to proceed?

PLEASE HELP!!!
