I am 13 years old, and I've been feeling like this since around the age of ten or eleven. It was never this bad. Now I constantly feel weighed down and stressed. I get sharp really painful chest pains about one to three times a month. Sometimes when I'm active I'll feel really ill. I get shortness of breath, I don't wheeze although breathing does hurt, I get pain in my stomach, and the feeling that I need to just lay down and....well...sleep or do nothing. Despite this, I'm active 5 days a week. I have no problems sleeping. I don't worry about much. I don't hate life. Life is pretty great, just stressing. Haha.. Sometimes I get a sour feeling and taste around my stomach and throat. On an unrelated note, I also commonly see hallucinations, not hear of course. Sometimes I feel dizzy and lightheaded, I am not particularly dehydrated either. I've had constant headaches ever since I moved south, closer to the equator. My eyes are constantly dry and sting. Occasionally my jaw will make a cracking noise and hurt, it's usually the left side. It's almost like popping, but much more unpleasant and it sounds more like wood splitting. I've also had pain directly under my cheekbones a few times. My family is not one to go to the doctor or any hospital at all, and I've never had a short or a check-up before. When I don't feel like wonderful life is a drag, I'm perfectly healthy. A lot if symptoms may or may not be either in my head or related.  Thanks to anyone who might know, or anyone who talks to me.
