Idk what’s wrong with me.

This pregnancy has been sooo much harder than with my first. I have a son already whose 3 and this one is a boy due May 11th. Every time I go to get my nails done or my lashes filled in, I sit down and immediately get hot and start freaking out and worried I’m gonna start throwing up. One of my worse fears is throwing up in public places. Lol it sounds sooo dumb. But I don’t know if I’m having an anxiety attack or what. I have mixed anxiety and depression history. I’ve still been taking a 150 mg Wellbutrin once a day when I used to take 2 of those. I went down to 1 in September and didn’t really have any issues. But this whole pregnancy has been different, I’ve also had issue with eating and my appetite and I’ve lost 10 pounds since finding out I was pregnant. I’m going to be 18 weeks Tuesday, should I discuss this with a doctor? They were trying to get me off Wellbutrin completely.
