Mirena and false pregnancy

I had my mirena inserted July 2006. Not noticing any real problems until recently, I have inquired just to be sure. Upon insertion I only had about 10 minutes of pain, and was fine for a while, like almost a year. First, I started getting migraines and had never had one before until 2007. Then fatigue set in. Chronic fatigue, foul smelling discharge, abdominal pain, back pain. Recently there were serious mood swings and they feel uncontrollable, and this is not fair to my husband or daughter. My daughter is three years old and i don't have the energy to play with her or the patience to deal with her. I feel like a failure of a mom because of the mood swings, fatigue, and depression. I have been married for almost 6 years and I have suddenly lost my sexual urges, they just fell off, and the way we were going I thought that that would never happen. But the thing that concerns me the most is the lack of period. I know they say that they will lessen but I haven't had a period since October 2008. Your period is a means of releasing waste, so I have pent up waste not going anywhere. Nausea set in between September and October 2008. I am constantly depressed and stressed for no reason my life is good. My husband has done some research because he said that all of a sudden I wasn't my normal self. I was put on medication for depression and none of the dosages worked, that is sad. We have agreed to have this "thing" removed. I would much rather try some condoms or even get pregnant again than to be a whole new person that I nor anyone else enjoys.
