People don’t respect boundaries

Hey everyone, I just really need to vent and maybe get advice on how to handle things.

So I’m visiting family for a little (everyone got the Covid test that I’m seeing and quarantined before hand) well a family friend that’s my grandmas age came over. This is the first time meeting my newborn. Well I’ve had major pp anxiety and I’ve been open about it, for some reason i struggle with people holding my baby that’s not myself or my husband, but I’ve said that if people ask and are respectful then no problem. She came over, of course oooo’d and aaaaaah’d at my baby but then started to take pictures, didn’t ask, but I let it go. After the 20th picture, a video, poking my baby’s stomach non stop, getting too close to me and to close for my comfort , I said it was enough and she did NOT TAKE NO, I covered my baby’s face even to try to get it to stop. I literally had to run to my own mother to HIDE BEHIND so she could help me. I know the family friend means well and is just excited which I’m happy about but damn.. I’m now feeding my baby in the back room and crying because it just really got to me. It scared me in a way..

Anyone else deal with this? What do I do? My anxiety is now through the roof..
