Stressed out vent!

Venting here. I'm 30 weeks 3 days with my first and stressed out beyond possibility. Okay in May I signed a 2 year lease for my mom and I on a 2 bedroom condo. I'm the youngest of 3 kids. But anyways my mom got a kidney from my brother may 16th. (Thank God!) now mind you both my siblings are homeless. Well after 3 days my brother got out the hospital and I said he could stay at my place until he healed, my mom had complications so I stayed at the hospital with her, (lost my job Bc my pain in the ass sister wouldn't even come up there) but around mid June my mom got released. She came home YAY! Well about 2 weeks after that my sister was still bouncing from home to home with her 5 kids so my mom said she could come here FOR A FEW DAYS! Remember this is a 2 bed 1 bath condo. Barely enough room for me and my mom but whatever. Here we are a whole month later, me nearing my due date wanting to nest but can't Bc my brother hasn't left, my sister and her 5 kids are here. Neither one is helping with rent or bills, my sister gets like 900$ worth of food stamps but only feed her kids and herself. My mom is also a diabetic on top of other illnesses and I was just diagnosed with gestational diabetes so we can't eat just anything but I've gone days without eating Bc savings and the little spending money we had are just about depleted. My mom acts like she's scared to tell them to leave but when I do they just ignore me. I can not bring a newborn into this. And my landlord wants to meet today but how with all these people here, she won't even leave for an hour. He might put us all out. Smh it's just too much going on right now and idk how much longer I can hold it together. Sorry for the long post and thank you for reading it! If you have any advice on what to do I'll take it all 😔
