Are these valid feelings or does my anxiety play a part?

So with my only pregnancy, I had really bad panic attacks I already dealt with an anxiety disorder, not sure if it was the hormones or the major stress I was under but I would literally get them even if I was alone. My daughter is about to be 4 years & I’ve became paranoid about getting pregnant again and going through the same thing that is literally ruining my relationship. This week I’m starting my anxiety meds, I’m just wondering if my feelings are “normal” or if my anxiety plays a major part in it? I also had preeclampsia but wasn’t severe so I also have thoughts on “what if I die during pregnancy or labor”
