what is wrong with me?!

[sunnies86]

I'm 21 years old and have always been healthy and active. Since the summer I started to develop breathing problems. I've been diagnosed with moderate COPD even though I've never smoked a day in my life. In addition to that, I have these episodes that come on suddenly with no warning and no pattern where I suddenly feel dizzy and light headed, get suddenly very hot and then very cold, and lack the strength to stand up. I have to sit wherever I am. The episodes usually last about 1 hour and then I'm fine, but am tired for the rest of the day. They started happening about a month apart, now it is once or twice a week. When it happens i have to eat something, anything. It doesn't make me feel better, but I get sort of an instinctual reaction to EAT. the last 3 weeks, when I get the episodes, my right leg jumps up and down and I can't control it no matter how hard I try. last week the left one did it instead of the right. Along with this, since summer, I've been increasingly tired everyday, now to the point where I can barely function. It takes so much effort to move or even eating seems like a big task. THen these last 2 weeks I am SO dizzy, to the point where I dont want to move or turn my head. It is so bad I feel like I want to cry...over being dizzy! I've had nearly everything checked and my doctor has now dumped my case and told me it's all in my head but i KNOW something big is wrong or I wouldn't be feeling like this. I feel so terrible and all I can do is sit in the house all day. I used to play basketball and soccer and go running and was busy from 8 am until midnight. Now I'm like an 80 year old woman. Except for my lungs and unexplained tachacardia, my blood tests are normal, my thyroid hormone is normal, my sugars are normal, and my ct scan of my adrenal is normal. HOWEVER, I have a "calcification" on my adrenal gland that has been there since 3 years before the symptoms started. the doctor says oh it's just scar tissue from having my gallbladder out 1 year ago, but she just doesn't get it that the spot was there BEFORE i had my gallbladder out. i'm frustrated and desperate. I'm not sure if i can even go to college in the fall with the way i'm feelig. please help! (ps: i do not think it's a panic attack. i know how those feel because i had one when i was 12. it's completely different.)

i forgot to add that i have bad joint pain in my hips and when the episodes happen my temples ache like someone is crushing my head.
