Will I ever be normal again?

My story started July 4, 2009. I was at the beach and even though I was only there for around an hour and went to the beach every wknd all day, I got really hot in seconds my heart was beating sooo fast and i couldnt catch my breath. I went in ambulance to the hospital and they said I had heat exhaustion, and even though it didn't add up I trusted them and went home cause I felt better. The next morning again my heart was beating out of my chest and I knew something was wrong but I had no ins. at time so i started trying to fix myself. Eat better, no caffine ect. In the next months things got worse, I started shaking, I was losing weight like crazy even though I was eating constantly I was anxious alot but when my hair started falling out I bucked and snorted until I finally got Human resourses to give me medicaid. I went to the health clinic first and they did thyroid and hormone test and all came back normal. Said I had anxiety and stress and to chill out. I knew they didn't care, didn't know me and I realized I had a long road before me. Within a week I was at ER my heart beating so fast I couldn't breathe but by the time I was scene It had stopped and they put me on 48 hr heart monitor which was normal. I winded up seeing another doctor gave all my symptoms and mind you this is in a 1 month period I have heart racing, throat swells but not all the time, I cannot stand the heat but have also noticed sometimes I get overly cold when noone else is. I AM GOING BALD!!!! I am never normal I am either anxious, feel like I want to rip someones head off for no reason or I am so tired I can't sit up. I finally seen a dr. who is referring me to endocrinologist but I can't get into see him for over a month. I don't know what to do. I have every symptom of hyperthyroidism test wouldn't show it but I know that I won't last till I see dr and have tests done. I need help like last month and I don't know what to do. Why isn't it showing on test I just knew the test would come back and show I had it. I am sick and can't function. I am missing work all the time and my being " I would say grumpy" but it's past that I want to put my fist through a wall and then I want to cry. Does anyone have any suggestions I am pulling at straws now.
