I want to leave my boyfriend

But he doesn't let me leave because of the baby. But he doesn't let me leave without the baby either. I just want to leave him cause he is in his grandmas house. She is a living hell. I'm about to do stuff that I don't want to cause I love my baby. But my boyfriend lets all the work to me all the time. And then he complains of everything that I do. I have been so preassured with school, food suply, cleaning, ordering my life and taking care of a baby alone that I have anxiety attacks. He just doesn't understand and I need advice cause I cant do it alone.
