Breaking down

I'm a single mom newly divorced. I'm 23 in school and working part time. My baby is addicted to me. Right now I had to go downstairs to cool off because he's been literally crying all day long and I just need to breathe before I lose it. I think i t has to do with my mom being on vacation because he keeps calling out for "gg". He's been waking up every night now I get like 3 hr of sleep now. Wish me luck.
