Yes all the side affects are more than likely coming from your Mirena.I had mine in for 6 months and at first it was o.k. until i got too the 5 -6 month i thought i was going insane i had bad depression,anxiety, i coulden eat my skin was off a yellow colour,suicidal thoughts and much more i didening put on any weight tho.
I have it out now and i did go through the (crash)this is still some side effects but im getting back to my normal selve slowly but surely.
My advice would be to have the awful thing removed asap you feel better in the long run.good luck.
