Feeling Judged/anxiety

I'm starting to think I may have post partum anxiety. I feel so paranoid that everyone is watching everything I do with my baby and judging me. From the stupidest things like changing my daughters diaper, how I dress her, how I carry her in her car seat. We were at a gathering the other day and my daughter was pretty fussy. I felt like everyone was just staring at me and judging me. My baby is pretty chubby and everyone was making comments on her size/weight which kind of upset me and also made me worry I'm feeding her too much. I cried driving home because I just felt like a terrible mom. Every negative comment someone says just replays over and over in my mind...I don't know if this is normal or I'm just being paranoid and I don't know how to make it stop 😔
