Thinking about getting mine out...is the IUC where my problems are coming from?

I have had my IUC now for almost a year. Since it was put in I have had severe acne, and I have never really had a pimple in my whole life, I have been super moody, depressed, no libido at all, in fact it just makes me mad when my husband tries to do anything anymore, I have no patience, and I am so fatigued no matter how much sleep I get, and I am gaining weight for no reason. Is all of this possibly a side effect from this thing?! If so, When I get it out how long does it take for all the side effects to start going away? I have asked my doctor but she says that all these symptoms couldnt possibly come from the IUC, of course not, the IUC is a big money maker for them. They push it like crack at that office. That is the whole reason I got one to begin with. They all made it sound like it was the greatest thing in the world. Guess not. But if anyone could give me a suggestion of what I can expect, or if this is really the problem, I would really appreciate it!

Thanks
