Twin pregnancy symptoms and conditions

Hi everyone, I just came upon all this yesterday and can't believe it! I have been thinking I am going crazy and have been going down a shame spiral! I have had the Mirena for about a year after the birth of my twins. When I first got the Mirena I really didn't seem to like it...I had weird bleeding, cramping, headaches but my doctor told me there were really no side effects except for the on and off again bleeding so I didn't think much of it. Soon, I started having heart palpitations and weird panicky feelings when I would be out places which I have never had before. I wrote it all off due to the rough twin pregnancy and moved on. Soon, I really started worrying something was wrong with me because of all these weird things, the headaches and heart palpitations and panicky feelings, also I started feeling foggy like I was walking around feeling out of it and sometimes a little dizzy or something just having weird head feelings. We always had in the back of our minds that it could be the Mirena but never really took action. Just for the past couple of months things have gotten much worse. Those panicky feelings really got worse and combined with anxiety and sad and crazy depression thoughts and feelings. I also have been feeling this weird nervousness.....even in my quietest moments of my day. This is so out of my normal character and I feel like I can't even remember what I used to feel like. I have been to my PCP who gave me medication for anxiety and have had a hard time adjusting because I just can't believe all of this craziness and I just keep thinking is the problem really my IUD? Then my mom came upon this because she just felt that me feeling this way is just to weird and I feel like I relate to all of your stories! I have truly been feeling like I am going crazy...and I have never felt this way before...ever. I called my doctor yesterday to talk with her and I am going to have this removed...although I am a little nervous about the after effects. I just keep thinking a year ago I was fine.. and now look at me...I am on anti-depressants...how did this happen?? I know that I have stress but there is no reason for me to be feeling this way. I would love to hear about anyone else who felt this way and got the IUD removed and how that went. I know that I probably won't feel better right away...but I am hoping with time I can forget all of this and move on.
