mirena questions

I have had Mirena for almost 7 months now. I am almost constantly in pain. On the left and right side of my pelvic area. I have my period whenever it wants to start and spot in between. I basically stay bleeding. I have lost weight because it makes me stay not hungry, depressed, gloomy, sad, among other negative feelings. I always feel like I am in a hole and can not get out. It hurts before and especially after intercourse. I stay tired, and my boyfriend thinks I am anemic. I wasn't like this before. The doctors try to tell me it is the "baby blues" but right before I got it and I had my daughter I was fine. Now I am 5'8", 115-120 pounds (the healthy weight is around 135-140) I am always tired and want to sleep. Never hungry, always sad, in pain, aggravated, have mood swings, hair loss, head aches, acne, irritable, losing weight. Some days I just want to lay in bed all day in the fetal position and cry. I never felt like this before and the only thing that has changed is my birth control. I searched through many sites to see if anyone else felt this way. Apparently many do. My boyfriend is to the point to where he wants to take it out himself. Can you do that? About how much does it cost for a doctor to do it? I have all these questions but no answers. I hope someone will read this and be able to possibly answer at least one.
Thank you,
