Hysterectomy or insanity.. I'm only 20!?

Ask the doc if you can have a Mirena IUD. That might solve your problems with pain, but it won't make you crazy because it releases just a little bit of progesterone constantly, and that progesterone is mainly absorbed by the uterus and doesn't go to your brain to affect your mood. It will most likely stop you from having any periods, which will be great for you!
