19f [F4M] stay at home mom , full time student, dead relationship

I have no clue where to start but here i am, I am 26 I have 2 children Im raising my sister and i have a 1.5 year old. My boyfriend thinks since Im a stay at home mom its literally my job to do everything and I am just so tired of having 3 kids. I have like 2 friends but I rarely ever talk to them because I just feel like a burden, so if anyone wants to chat about all the shit in their life hit me up!
