DAE have TMJ/Jaw Problem?

I've been in a constant state of stress/fight or flight since i was about thirteen, dealing with things that were too grown up for me and "taking care" of volatile people. sometime around age 16, i started experiencing constant jaw clicking, and it eventually developed into full blown constant jaw pain and discomfort. the clicking stopped, but the pain and tension is still very much there as i approach being 20. is this a physical manifestation of everything? does anyone else deal with this? i've been to physiotherapists and dental surgeons but they say there isn't much that can be done.
