I Am Hypothyroid With Fluctuations Between Hyper And Hypo. Have

I am hypothyroid with fluctuations between hyper and hypo. Have never had 2 tests be consistent, like a yo-yo. I really need to be able to get this working as my symptoms can change only to the point of me having insomnia when in hyper or suppressed mod. I can't seem to get anyone to understand what I am feeling and the change in my attitude. I blow up now when that is not how I usually am. Forgetful, have the sensation of my eyelid drooping. What is going on with me?
