Removal in 10 days and Im really nervous

So I've had the mirena since August 2018. I am getting it removed because I have already had to have one replaced because it migrated and got embedded into the lining of my uterus. Ive had an ovarian cyst that ended up cutting off the blood supply to my ovary causing it to have to be removed. Im just realizing that maybe the iud caused it and what if I get one on my one remaining ovary. Ive read that a lot of people felt better mentally after removal. I'm scared of the getting the mirena crash. What do I ask for to help with the symptoms?
