Feeling worse @ 4 months post????

Hey everyone...Just venting. I have had the worst week. I am guessing I'm having the dreaded 4 month Crash. I sure hope that is what it is. I just feel like I had a major setback. I almost feel worse than when I had the Mirena. It is a different worse though. I don't know how to explain it. My heart beats faster than normal, body buzzing, mild anxiety, feeling of mild vertigo, sensitive to cold weather, I also have been getting startled easy(I feel a shock go through me when this happens-Weird). The list goes on and on. Just the week before I thought I was on my way to recovery. Felt pretty good, normal. Then wham! Back to the beginning. It makes you question whether it is the mirena or something else. one would think that once you got it out, all would be fine. Not so! All I have to go by is the posts on here and the women before me that have been there and recovered!
