I just took a shower and when I was massaging conditioner in my hair, I ran my fingers from root to tip gently and a WHOLE BUNCH OF HAIR CAME OUT. I know that everyone loses hair in the shower, but this was like a scary amount. I already have thin hair and I don't want to lose any of it! Please help me, I'm super freaked out!!!

Info that might be useful...?

I use Dove shampoo and conditioner

Its normal for me to lose hair when I brush it

I live in a humid climate

I'm on my period right now

I've been drinking more water than usual

I have been super stressed and anxious lately, but that's been going on for quite a while
