Anxiety during pregnancy

I've been experiencing extreme anxiety the past couple weeks and yesterday I had a panic attack. The first one in a very long time. I went to the grocery store and all the sudden could not check out in fear of speaking with the cashier. This is something that I struggled with a few years ago but I thought I had gotten over it. Since I haven't wanted to go in public at all and the thought of my doctor appointment on Tuesday is scaring me. Is this something I should even mention to my doctor? I don't want her to think I'm over dramatic.
