I realized not everyone can be a mom. How do you women do it?

I love my son to death. He is 2 but I’m fucking exhausted. It really is a 24/7 job. I make sure to stay highly caffeinated to keep up with him, my job, finances, and the house. My husband left us last year so I don’t have any help. He wasn’t any help anyway financially and wasn’t present anyway. I always look like shit; don’t have time to shave my legs, armpits, and vagina. Sometimes I want to run away to a deserted island to just breathe.
