*Potential Trigger*
I have been experiencing nearly constant episodes of panic. When I try to do deep breathing, it actually makes the attack worse. I struggle to get air. Things have been extremely worse since the marriage counseling session last Thursday. I had a consult for a colonoscopy last Friday and spent an hour trying to make sure I had a female for the appointment. When my husband asked why, I commented that I didn't want some male doctor messing around 'back there'. He said well, you used to like doing that. I went full-blown panic and yelled for him to stop. He kept going. I was shaking and my vision went dark. I yelled for him to stop and he finally did. BUT, he didn't, and still doesn't, understand what was so wrong about what he did. My panic has been very, very much more difficult to deal with since then. He wants intimacy, but I can't. I'm beginning to think I may have to try to dissociate like I used to if only to appease him...
