Burned out

Just had my second Oct 18th and every time I have to get up and tend to my son I just hate my kid's father even more. My son will wake up at 12 then 2am then stay up until almost four eating about 8 oz 2bottles and still attempt to nurse. Wake up again at 6 until until 8 then I have to get up and tend to my oldest some days I take her to daycare other days I'm so sleepy deprived I dare not get behind the wheel her daycare has a 9am cut off time and I'm 25mins away. My mom shames me if I actually catch a nap during the day because my oldest is left up alone but she has eaten and is watching tv or keeping herself occupied. Idk idc if no one reads this it's just great to get it off my chest because I feel alone I'm exhausted and I'm frustrated. I have no help my mom is supposed to be helping but she sleeps more than the baby I cook clean and still do everything around the house during the day with maybe 4-5hrs sleep from 12am-8:30am. Still pumping still nursing I'm ready to stop nursing because it's just another stresser. Up right now been up since a quarter til two. I refuse to cry but I am annoyed as hell my mom has me here and she doesn't even help that's just beyond me
