Anxiety while pregnant

So I had an anxiety disorder before I got pregnant but I had it wayyy under control now since I have gotten pregnant it seems to have went hay wire. Every ache ad pain I feel literally insights anxiety in me and I don't mean normal worry but heavy hard to breathe feeling sick anxiety. I don't know why and I know it doesn't make sense but I don't know how to control it. My techniques from before aren't working. Like now. I burnt my throat eating some soup and now it hurts when I swallow. Every time I swallow I feel fear run threw my body. I am trying breathing techniques and focusing on other things but it isn't going away. Someone please tell me I am not alone in this.
