Thank God for Google and these websites. I had the mirena placed in April of '08. I have and still have the severe cramping, the bleeding, the low libido. But as of Saturday a new symptom has arrived. I am having some bad anxiety. I am a very strong, super happy, loving person and have never had anxiety. And since Saturday it hasn't stopped. I have this absolutely awful feeling of dread. I called my doctor to set-up an appointment with a therapist as I am starting to really get scared that this won't ever go away. And then I started thinking and googled mirena side effects; just to have a look. And lo and behold, there are many of you with the same thing. You have NO IDEA how grateful I am to learn this. I truly thought I was going crazy or would have to be put on some medication. I made the appointment and this shit is coming out tomorrow morning!!! THANK YOU! If anyone could answer this question, how long until you felt "normal" again???
