Any Ideas of what I might have?

I'm so sick of taking pills, all at different times o boy! i take synthroid before i eat, ciprelex after i eat and antibiotic for a new UTI, (1 two hrs after ciprlex and 1 two hours before bed.) then wellbutrin right before bed...it seems like all my doctor does is treat symptoms but not try and figure it out, and when he is interested in the symptoms together he always asks me what I think it is....he's the one that took 7 years of medical school... I have electric shock like pains that seem like neuropathic pains, Hashimoto's, Fibromyalgia, and the blood tests detected another autoimmune. I'm always tired, and my muscles aside from the electric shocks are sore/throbbing all over. since I've been started on the wellbutrin I rarely have eletric shock pains but when they do come they're bad. and Now Im having tightness and stabbing pain in my chest so bad I almost couldnt breathe, I went to the ER and they couldn't find anything. I felt like my heart would explode... :( a week before that I had what felt like a thunderbolt stabbing pain in my back I could hardly move, when my head leaned forward it hurt worse...I have tested positive for ANA,ENA, and have low iron and low potassium

The doctors are dumbfounded and so I'm going to see the doctor tomorrow at 1 but before that I'm wondering if any of you have any idea? tests he should run? what it might be? anything?
