Case Scenerio: Do you think I have an eating disorder?

During infantcy I had an few accident that tossed my posture off a bit, after I grew I fixed the problem and have excellent posture but I'm 5'10" and when I reach or exceed 134 lbs. I have tinnitus (ringing ear noises) and my jaw and joints crack and pop and I get TMJ problems. As a result I always try to keep myself between 126 to 130 lbs, I exercise daily (often over exercise) and am extremely fit, but I consume less than 600 calories per day and fast when I exceed 130 lbs. Even when weight is on me due to pure muscle m I run into the same problems and feel horrible, so to keep weight I care less how the weight comes off as long as its off. I take supplemental vitamins and herbs daily and eat nutritously so my nutrition levels are quite high. I often think I am fat when exceeding 130 lbs. but that has become learned behavior to help me maintain weight. My bone ends at joints are slightly misformed so there isn't a good solution. Do you think I am anorexic or have an ED?
