Need to rant - feel i’m going mad

I’m staying with my parents, brother and coming to 1yr old baby. Hubby is not with me as we are in a LDR. It has been a living hell staying with my brother. Prior to this, it was just the both of us as my parents were overseas due to Covid. When baby was born, I had to cope caring for baby and household chores on my own. No complains coz these are tasks that needs to be done. Problem arise when I did this chores (wash clothes, bottles, hang clothes, etc) past midnight. I don’t have a choice because i’m managing baby on my own with no help. I can only do chores when baby is asleep. Fast forward when baby is 6mths old, parents came down to help. Brother still creating problems. There is no compromise as I had to be the one giving in all the time. Worst still, parents did nothing to help with the situation. They hope that we don’t argue and pretend as though nothing happen. Recently, he cursed my 9mth old to die. Adults are fighting but yet my poor baby got cursed to death. Parents did nothing. Few days back, in other to aggrevate me, he intentionally blast his hp game at 12am. This didn’t bother me. When i brought this up to my parents, i’m being told to tolerate or move out. Wtf? I don’t know how long more i can cope with this situation. All my dad said was to ignore him. It was in spite of anger that wrong words were being used. 🤯🤯🤯 Am i thinking too much? I need help but yet i’m not sure what i need to do. I can’t possibly move out now on my own because of logistics. I need to work, find infant care (assuming i no longer get my parents to help), pack belongings, find new plc to stay, etc. This is just too much for me to manage. I have already exhaust almost all my leave. I feel like i have no where to go. 🥺
