I am so very sorry you're going through this. I've never been in that situation, but I am here if you want to talk. I'm sending you and your H big hugs right now.
This absolutely made my day. Thank you!
There are a bunch of different reasons why that could be happening. Maybe you should talk to your doctor. FWIW, I guarantee other people have done this. You are not alone. (That wasn't mean to trivialize what you're going through.)
