Is it possible you are anemic? It would explain some of the tiredness. I totally agree with the doctor thing. If you are not satisfied definitely go to a different doctor. If you feel you aren't being taken seriously or not getting the care you think you should, immediately look for a new doctor. Your health and well being is top priority.

You may have more than one thing wrong too so keep that in mind - each would make the other worse.

The sleep thing sounds like sleep apnea & that includes being tired all day & it would impact on your ability to & response to exercise. It could also be hepatitis or I don't know the "right" name but "sleeping sickness".

The pains could be from a number of things - but eyes - i'd check cholesterol & also for diabetes (regardless of how healthy you are some peoples systems just don't function properly & they can get these peoblems due to that or hereditary genetic problems).

The chest pains don't seem to fit - being 21 & "fit" you may overreact to pain or be able to "stand" it so underreact so it could be stress (worry about all this - which by the way could also cause the eye symptoms) or heart issues due to stress or cholesterol or other more serious issues.

Before you see your dr or a new one!! Try to keep a journal recording when these various symptoms occur, what you have been doing & eating & drinking (at 21 - patying drs will sasume drunk possibly even drugged etc & if this is not the case you need to really tell them this but if there are - or have been - drugs heavy alcohol use the dr needs to know this as it may be the cause of your problem!!). The journal should also mention food intake - what how much & time - there a re a number of auto-immune disorders (not aids) like irritable bowel syndrome to name just one that can cause all sorts of problems.

Have you lost/gained any weight since this started? Did anything happen to change or affect your life about the time this started - anything?

Do not hesitate to see another dr - I was deaf for 10 years drs kept saying I was fine till finally we found one that would acknowledge the problem - look beyond appearances - 12 operations later I was basically fine!! My daughter last year lost alot of weight so the drs said anorexia - after all - teenage girl what else sould it be - regardless of the fact that their own tests showed her to be eating & keeping it down etc etc - I discharged her & threatened legal action - she self-diagnosed aftermuch research irritable bowel - she's gone down to 32kg (about 68lbs) once she stopped eating the stuff the drs ordered her to eat & ent onto the ibs diet she immediately regained weight (actually abit much!!) - but she's still traumatized by the treatment last year at the hands of so-called specialists.

I told you this as a warning - you wouldn't leave your car in the hands of a mechanic you didn't trust would you? So isn't your body, your life more important than your car? Find a dr who will listen & do tests - blood, urine, hormone levels, x-rays etc.
