Weird feeling when touching nipples

So I'm 16 weeks and I noticed something last night. I have dried colostrum on my nipples and I started pulling it off, which can be difficult but it doesn't hurt. My nipples are VERY sensitive right now and I wouldn't touch them without reason. But the colostrum was really bothering me so I wanted to get it off.

I noticed last night that when I try to pull it off this weird sense of dread washes over me, like I feel a bit shaky and like I'll never be happy again. I know some of it has to do with the effect it has on my nerve endings but it's just so WEIRD. I thought maybe it was a fluke but I started doing it again just now and I had the same feeling. Kind of like if a dementor was nearby, if that makes sense lol. Has anyone experienced something similar? I read something online that kind of reminded me of it so wanted to see if I wasn't alone. This is so fucking weird
