Lord, I starting to think I have baby blues

I looked up symptoms and I only have one listed so far, but there's no telling when I might start showing others, can anyone help me with this I've had 2 older children and didn't have it with either but that was over 8 years ago and I'm older now and noticing a difference this time around?

I feel like I can't be around big crowds of people and I feel anxious alot of times
I don't feel this towards the baby, just toward everyone else around me
