I just want to let you know you aren't the only one. I am like this with my husband. So, afraid he will cheat and he has giving me no reason to feel that way. It is physical exhaust and I get panic attacks during my "attacks". I call them "attacks", because it doesn't happen everyday or week. I know it can be horrible feeling. What I have done is put a rubber band or if you really want to hide it one of those new silly bandz on my wrist. When I get the feeling I snap it walk away count to 20. Try to figure out why I have to do this and why I really don't. I hope this helps. It is work in progress for me.
