Panick Attach???

Ash
Ok. So I never have panick attacks and I think I just had one. I keep dwelling on my numbers doubling and any little pain I have scares the shit out of me. This damn MC I had in December really has me bent out of shape. I started to think the worse because I had arm pain not shoulder tip pain and it's super dull. So I started to sweat, feel nauseous, heart started to race, I was lightheaded. Then I took deep breaths and ate a banana and I feel fine. Still have this weird burning sensation in my arm right below the shoulder tip but I could have just tweaked something. My second set of bloods is today and I should know tomorrow what's going on. 
Why is this so hard for me? I just want to curl up in a bubble until I'm ready to give birth.
