I’m going insane....

So I’m living with my bfs parents I have two kids and they basically take over my parenting role and tell me what I should and shouldn’t do with them. I feel like I’m not even a mother at all. I feel like as if Im treated like a kid and feel like they don’t think I can take care of my kids didn’t so they have to step in. I have gotten sick of this and just feel like crying all the time and so uncomfortable I try to talk to my bf and tell him how I feel he says I’m crazy and just need to relax when the feeling is never going to go away. I’m sick of feeling like I always have to live up to their expectations and can’t be happy and alone with the kids or my boyfriend... hard to save money right now for a house that’s why I’m living with them. But I’m at a point where I can’t take it anymore and not sure if I should apply for singlet mothers apartment or low income apartment I really just need out of here.
