I saw your post here and wanted to reply. I was just diagnosed 3 months ago with hashimotos. It is an autoimmune disease where my antibodies are attacking my thyroid. I'm not hypothyroid yet but my dr. says one day I will be. I lost lots of hair before being diagnosed and still continue to lose after being on meds for 3 months. I cry myself to sleep as well. My doc says I need to give it more time to work. Hair goes thru different cycles and it will take a while to get it back. I take good vitamins, evening primrose oil and fish oil each day. I also eat healthy and try to get good sleep and exercise 4 days a week. I have not experienced the weight gain like you so not much help there. Try to exercise and eat very well and you will see results. Take control over the disease and don't let it control you!!!!!! I'm sure you are a beautiful girl!! Keep your chin up. I hope this helps you!!
