protruding eye

approx 5years ago I was diagnosed with an overactive thyroid, I had all the classic symptoms and a protruding eye. this went away after a couple of years but it shattered my confidence, I was then given radio iodine therapy over 2years ago which resulted in my thyroid becoming underactive. since then my medication (levothyroxine) has been slowly increased as the gp said I wasn't on the correct dose. it was increased from 50mcg up to 125mcg. the doctor said 125mcg was the correct dose for me but within 6weeks of him saying this my eye started to protrude again and I was getting heart palpitations and becoming depressed so I went back to the doctor who basically said there was nothing wrong with me, it couldn't happen that quickly, arrange my own blood tests if it made me feel better and made me feel like I shouldn't have bothered him n I was concerned for vanity reasons only. I was so upset I left the gp surgery and havent been back, I cut my medication myself to 75mcg almost 2months ago but there has been no improvement yet. will my eye get better? or will it stay like this? I know there are worse things in the world but for a girl who had very little confidence anyway this has shattered me yet again.i don't even want to leave the house because people cant even have a conversation with me without staring. can anyone help?
