what do i do ??

I'm 9 weeks pregnant with my first baby and i live with my boyfriend and his family and I help out around the house as much as I can. if there's something that hasn't been cleaned I clean it and if something needs to be done I do it,I even do his mom's laundry if it needs to be done because the only was I can do ours is if hers is done and she's always talking shit about me and bashing on me and saying I'm lazy and don't do anything but sleep all day and that's far from the truth and it's so stressful. and because of what his mom is always saying he's starting to i don't do anything when I do literally everything for him. and and even the littlest things set him off. and it stresses me out so much I don't know what to do.
