You described your symptoms and story very well! I also have had most (truly almost all) of what you described. My reaction was heavily neurological. Nile gives the best advice, and I can't really add to her thoughts. I am 4 years post, and still not back to normal, but getting closer. In general every year has been better, but I still have some difficult times (this month for example). Reading your post brings back a lot of memories.
My IUD was floating in my uterus, and it was a huge mess to get it out. I hope you can have yours removed very soon.
This forum is not highly active, but I still check it regularly. Keep posting; I'd love to know how you're doing.
