3rd pregnancy struggles

I feel like I’m doing a terrible job with my 3 year old and my 10 month old. I used to be so patient and laid back and my 3 year old just listened so well and was so easy

I’m struggling so much thinking I’m bringing a 3rd baby into this world and I can’t get anything done at home without somebody constantly needing me, crying, my house is a wreck, I can’t take care of myself efficiently (like lucky to get a shower every couple of days, drink enough water, make sure I brush my teeth, etc) I feel like an awful mom and like I’m not built for this anymore

Literally just found out I was pregnant and I’ve been SO emotional, having headaches, exhausted.

I was soooo useless was in my last pregnancy, I hardly had the energy to exist most days 😩 it feels so unfair to put my 3 year old through this again and now my 10 month old

How do you do it? I am so scared!!! I always wanted a big family but maybe I’m just not cut out for it
