35 weeks and constantly dizzy/lightheaded

Anyone else going through this? I’ve had episodes through the pregnancy of feeling faint and lightheaded here and there, but as of a couple days ago, it’s now constant. Even having to sleep propped up. I had a midwives appointment today and was feeling faint while there to the point of starting to sweat and unable to stand but blood pressure was completely normal. She didn’t seem too concerned.

I have anxiety and panic disorder, and feeling faint brings on panic (because one of my biggest fears is passing out).

I want my girl out of my uterus and in my arms so this will stop!!
