30 weeks and extremely anxious

Every time someone brings up anything to do with the baby arriving I get so anxious. Like yesterday I was talking to the lady doing my maternity shoot and I had to take a break because my chest was gonna cave in. Or well I thought it was. Or when people ask me about a name I cringe because we don't have one. We are also moving into our new house by the end of august! I'm not really sure why I'm feeling like this. Is this pregnancy or me being over dramatic?
