Muscle twinges symptoms and conditions

I was diagnosed with having hypothyroidism, and after having FNAs done on the two nodules that were found during a screening of my thyroid - it turned out that I also have Hashimoto's Disease. I am currently on the lowest dosage of Levoxyl - and have been for about two months, and I have never felt so bad in my whole life. Yesterday I cried the entire day - for no reason. I have migraines several times a day. I get dizzy and have hot flashes and I feel so ditzy lately, forgetting the littlest things. It is a very frustrating way to live, being married with two small children. It is hard for me to explain this to anyone, and I unfortunately take some comfort in reading that I am not the only one living with this. I keep wondering if I will get better, not only for me, but for the sake of my family.
