You just described everything that's been happening to me to a T! Except I've only had it in 11 months, my periods come completely randomly still, and range anywhere from barely there to torrential bleeding. My back pain has started to get to the point where curling up is the only thing that relieves it, and my face is breaking out so bad that I had a doctor think i had some wretched bacterial infection. I also have no energy, but yet can't seem to sleep. And have lost almost all motivation to do anything, at all. I thought I was going crazy or just maybe coming down with depression, but now I'm thinking that's not the case. I'm only 24 and haven't had the chance to have a family yet, but I think if I want that option in the future, Mirena has to go!
