Hair still falling out PP

I’m 16 months pp and my hair is still falling out a lot. Mainly in the shower. It’s like whenever I shower it’s just non stop hair falling out, a bunch of it in the drain. I could understand if I had long hair or a lot of hair, but I have short thin hair already so to see all this hair fall out while showering is pretty scary. Maybe it’s because I’m still BFing? I don’t think there’d be any correlation but maybe? Also I do have some stress and anxiety.

Any ideas on why this is happening or how to help it?
