Hair loss! Almost 5 months postpartum

I have a 4 month old almost 5 months on the 12th of this month. Exactly when my little boy turned 4 months I started to loss hair I noticed because I can see it in the floor! Also when I brushed my hair hair just started falling out like nothing. My hair is already thin!! Probably like 4 1/2 months is when I noticed how much hair would come out while I showered! I feel like it’s just getting worse I stopped taking my prenatals well I didn’t stop I just forget but I try my best to take it when I remember. I honestly don’t eat really good I really don’t know why I might me suffering from ppd. Sometimes I just want to cry sometimes I don’t want to eat at all. I have also been stressed. But I really want healthy hair I know you loss hair after but I feel like I’m just losing way to much. Is there anything else I can do? I will insert pictures of how much hair I lost tonight while I showered😭😭 also I do not breastfeed my baby is bottle fed.
