I'm so stressed I don't know what to do anymore

I feel like everyone takes advantage of me, my problem is I am too nice. My mom takes advantage of me, and my boyfriend. First of all my mom is really jealous of me. I live an ambitious life style. I work, finishing up my last year at an amazing university, and I'm pregnant been in a 5 year relationship. I'm 32 weeks pregnant. Im having a baby shower August 14 and my mom has been telling my family not to go to my baby shower. My aunt was the one who told me this. My mom is money hungry, she been trying to pull money away from me. She was mad cause I didn't want to pay her bills. She over works me, telling me how she so tired and how she needs all this help. I only work part time and I'm taking this time I'm going on maternity leave to work on myself, my baby and online schooling. Then there my bf who is also money hungry. He lost his job Monday. And he's been sucking money out of me like I'm an ATM. Now I have no money at all. I'm having my baby shower at a 5 star restaurant I used to work. I got the small dining room for free, everyone has to pay for there food. I don't know how, Imma survive this. My boyfriend been acting weird, and I just want to run away. I don't know what to do. I had mental break down and I throw up. My anxiety symptoms extremely high. Cause I have no money. I want to leave his parents house and I want to live a simple happy life.
