underactive thyroid

Does anyone else on here have an underactive or overactive thyroid?? I had overactive, did the iodine treatment when I was 17 and now have an underactive thyroid. It's been up and down lately.. some days I don't want to leave my bed and others I feel fine.. but I've noticed a lot of weight gain and I've been struggling to gain the energy to work it off and even when I do workout and eat healthy I never see any change. What can I do to boost my energy.. what can I do to sleep better at night and not feel so depressed.. doctors never help.. I just feel really helpless at this point.. my family doctor will not change my prescription says I'm "fine" and my specialist is a 6 month wait list.. I'm really starting to get discouraged and depressed.. I just started school so I want to stay healthy and do well.. if anyone is going through the same thing, please message me 💕
