Anxiety disorder

I'm not diagnosed with anxiety disorder, but that's because I've never gone to a dr for my anxiety. If I get a bug bite, or if my son gets sick or a rash, I freak out. Not just get upset, but I start breaking out in hives and get hot flashes and nauseous and sometimes lightheaded. It had never been bad until I got pregnant. (I assume hormones can make the anxiety more intense.) Does anyone else have anxiety or panic attacks like mine? If so, what did your dr do for it?
