I was diagnosed with hypothyroidism when I was 8, I'm 20 now. I've been on the same prescription the whole time, but I've never felt any relief from the symptoms. I'm always tired, I have no energy, some depression, dry skin, intolerance to heat and cold, etc. I've been to several doctors, and mentioned it. All they say is that the thyroid medicine should take care of it and that's the end of the conversation.
