Advair Diskus and emotional wreck

I started taking Advair 250/50 when I couldn't get any air in the upper part of my lungs. I was diagnosed with asthma as a child, but hadn't experienced it since I was 11. I am 21 now, and I have panic attacks, pain in legs (pain in my thighs, and it feels like a rubber band wrapped around my knees) and arms, splitting headaches, hyper-sensitivity, mood swings, back pain, heart racing for no reason(especially at night, it wakes me up), insomnia, pain in my chest (mostly on the left side near my arm pit that feels like muscle tightness), I sometimes get sharp pain in my chest if I take a deep breath, I've gained 40 lbs. in the past 8 months, and I am a nervous, emotional wreck. A year and a half ago, I was a completely different person. I've been to the doctor, and they can't find anything wrong with me. Although I am overweight now, my cholesterol and blood pressure are perfect, there is nothing wrong with my lungs (barring asthma). I am in great health, and yet I feel awful. All the time. I have no idea what to do, because my doctor's have told me that the only known side effects of Advair is potential damage to the teeth. I am outraged, but I am afraid to stop taking it because my lungs actually hurt when I don't. I'm also on an Intal Inhaler, but I haven't heard any side effects of this. Here's the kicker, the doctor that prescribed me the Advair wasn't even a respiratory specialist, and refused to reccomend me to one! I'm so glad I found this site because everything everyone has listed seems to be what has gone wrong for me since I started taking it. If anyone has any information on how they're doing now that they've stopped taking it, or the "withdrawal" effects of Advair, please post them. I'm hoping to wean myself off. Good luck to all of you, and thank you. Now I can stop being so worried that I have blod clots, lung cancer, or an aneurism. ;)

Thanks so much,
