Severe anxiety at 36 weeks

All of a sudden I have this severe irrational sense of impending doom and panic over the last few days. This is overlying this weird quiet sadness. I noticed I’m quieter and kinda down? I can’t fully explain it but I am not myself.

The feelings are not about any specific thing but it’s also about everything (including non-pregnancy things). I can’t work through any single issue because something else just pops into my head.

I read that anxiety late in pregnancy is normal due to hormone shifts but I was wondering…

Am I going to feel like this for 4 more weeks or do we think it’s a sign labor is soon??

I don’t think I can feel this way for a month and remain sane. It’s not healthy!
