Hello.
There are a many reports of side effects of Mirena, which you have also described. It is mainly the hormonal imbalance that plays a role in producing these effects.
I think the best step would be to consult your Obstetrician/Gynecologist for these problems. If there are other alternatives available, they are worth considering.
Regards
I can't answer your question but wanted to say somebody just posted a question about this very same thing a few weeks ago. My friend had the Mirena placed and within a few months her whole personality changed. She was so depressed and anxious she almost lost her job. She was a completely different person. She did not have it removed but she is now on an antidepressant and she has returned to normal. I don't know if it was the cause but she was a completely normal person prior to Mirena.
