Mirena and friendships

Let me just say that like so many other women on this site I have been stressing over the predicament that Mirena has put us in. Yes, I was warned about having not had children that I am not a good candidate for it but I am in my early twenties and don't want children any time soon and I had been on Depo shots for as long as my Dr. would let me, so don't judge. The fact of the matter is that for the past two years since the insertion I have wondered what the hell is wrong with me!!! I have been extremely moody, depressed, and have had several strange symptoms including headaches, acne, weight gain, and the overall feeling of someone in the nineties instead of being 22. I have never been a lazy person or someone prone to acne. I have been to the doctor several times and she keeps saying it's not Mirena; I'm not convinced!!! I have not had a menstrual cycle since I started depo five years ago, you would think I would be a happy person but I'm not. I don't know what to do, I'm afraid to take it out and be wrong about it and get pregnant. But on the other hand I'm severely depressed about the weight gain and the more and more I exercise and diet doesn't matter. I have gained over 20 pounds and gone up 2 dress sizes, because of this I don't feel like having sex because I'm tired or I don't feel sexy. My marriage is suffering from my mood swings, lack of libido, and not wanting to do fun things people my age do. I've lost several friendships by not wanting to leave the house, I feel like it's starting to take over my entire life. I thought it was just me having these problems but the more I read other peoples posts the more I feel like I'm not alone. You don't have to be forty and have 3 kids to know what it feels like to have symptoms like this and be told over and over it's just in your head. Thanks to every one who wrote on this web site, it's comforting to know you're not the only one having problems. When I get it removed I will post again with how it has changed.
