Antibody test symptoms and conditions

I have been on Levoxyl for about 9 years and have felt awful. I have had weight loss, dry hair, thinning hair,dry skin, muscle aches, migraines and the list goes on. I just got out of the hospital Monday after 4 days of testing of my heart and lungs. I was admitted for racing heart. The doctor's conclusion was anxiety! They said that Levoxyl has nothing to do with my rapid heart rate. The endocrinologist prescribed taking levoxyl .050 on day and .075 the next also a beta blocker, Xanax and Zoloft. I can not take any of these meds b/c they make it almost worse. I KNOW it is not Anxiety and it from the Levoxyl but what do I do?? I am a mess right now can not be in this condition with four young kids and a husband. None of the doctors would say it was the Levoxyl and instead prescribed more and told me to check up with blood work in 6 weeks. I took the .050 yesterday around noon and by 7:30pm my heart rate picked up again and continued until 4:30 this morning. I can not sleep more then 2 hours at a time and wakeup feeling like I am crawling out of my skin. PLEASE let me know of any solutions.

Let me tell you guys It has been horrible for me.
a) My doctor gave me a Zpak for a strep throat it was gone in a few days.
But a few weeks later I had a stomach pains that would not go away so then the doctor did a test for H Pylori the antibody test came back positive so then I was on PrevPak(which has Azithromycin) after the 2 week period of these drugs I had a infection come up in my growing area, had burning pain for peeing. It sucked because I was on a trip to Universal Studios and was in Miami for New Years Eve. Well after this went away I had another infection come again in the growing and now its finally starting to go away after the doctor gave me some fugal pills and medications for it. What a nigthmare. With all this going I had diary and hemoroids nasty situation and normally have mouth ulcers so can you image the past two months have been hell for me!!!
