Already sick of this

So i am currently six weeks pregnant and we live with my bfs sister and then her boyfriend moved in along with her two kids that she barerly has bc she goes out and does whatever she wants instead od taking care od the kids. She is always wanting to borrow money from us. We buy the groceries laundry detrgent car insurence for our car plus the rent for all of us. All she does is start arguments, fights and hounds us for money that she doesnt need for stuff that she doesnt need, and it causes so much stress on me. And im so ready for us to get our own place in two weeks and honestly two weeks cant come soon enough!!! Not to mention mt rubs ache, i have nasea all day every day, and headache and no appetite at all. Ugh
