She will get through the crash but she will have to take steps in order to get better. She should go to the doctor and get some testings done on her thyroid ect. I personally wanted to die because I could deal with the side effects. I went to a reiki session and reflexology and at the end she said my uterus and stomach seemed to have problems. I did acupuncture and massages. I recommend magnesium supplements, vit b complex vitamins, chia and flaxseeds, omega 3 foods, switch to organic foods and meats. You can go to the doctor and see if the vit are ok for her to take. It helped me and I think in one more month I will be myself again. I love how the people that suffer because of the mirena they just brush it as small side effects. I took other birth control pills are was fine except I was a little moody.
