Hypothyroidism Has Turned Me Into A Zombie

I have been Hypothyroid for about two years now. It hasn't been pleasant. I have been on different medicines, seen different doctors and specialists, and slept alot of my life away. I used to sleep six or seven hours a day. Now I sleep ten to fourteen hours a day. I am currently on Synthroid, which I think is working better than the Armour and the Levothyroxine. But I still have this tiredness that never goes away. I gained 30 lbs. before being diagnosed. Now I have lost 15 but my weight really feels out of my control at this time. The depression I experienced once I was diagnosed caused me to be on antidepressants now too. I go through periods of time where I give up on trying to fix myself and just accept that this is just the way my life will always be from now on. The need for a nap on a daily basis is just the way I am. Then I find myself a few months later saying, wait a minute I shouldnt have to feel this bad. There must be something else wrong with me that the doctors just cant find yet. I mean the symptoms sound strange to me. I gain or cant loose weight, my body aches, I am tired all the time, my hair is falling out, I get tingling in various places of my body, I have weird muscle spasms, suffer from depression, get bouts of constipation, I am sensitive to both hot and cold and varying times, and my periods are more severe. I have had two different doctors say to me, I dont know where else to look for why you are tired all the time. It is just frustrating.
