How do I cope with the stress and crying?

I have 2 toddlers, ( 1 autism the other neurotypical) I love them but like most kids they're really demanding. They cry in unison, I have to deal with being overly touched,poked,bitten and pulled on and I have toxic family that berates me, I'm trying to get them in daycare by January without losing my mind.

I have no help. Daycare is my only form of help and even then I worry about neglect qnd what not. I really feel like I'm going to go batshit crazy.

Tips please.

I feel like if I cry or show weakness I'll lose it. Plus my family tells no one is gonna feel sorry for me so it's not a safe space to cry.
