I've been really on edge the last couple days. I feel afraid of my husband (he has never given me a reason to be afraid)

But I can sense this is more than that, I feel hyper vigilant when people are in my bubble, I feel like my body is on high alert always.
I am exhausted and I feel like I'm spiraling.

I don't know how to help my husband understand its not him or his fault.

Does anyone have any thoughts?
