I just feel lost

Devin • Due May 28th with Aubrynn Mae 🎀
I've been staying with my mother because my SO lives with his grandma for now and the stress there is overwhelming for me. Well I got word from my mom today I needed to move in with my dad (3 hours away from her and my SO because her and her fiancé are breaking up and we're out a home) and I'm at my dads now visiting. I go back tomorrow and I'm getting my things and I'm going to stay with my SO for a night or two then go back to my dads. My dads ex girlfriends son lives here because his mom is a crack head and this was the only home he knew. He is moving out for college in August. I'm moving back up Friday and I'm getting my daughters side of the room set up and everything and the father will just be back and forth until he can get us a house which we don't know how long that will take since he goes to court the 29th for joint custody of his 2 year old and he's going to be paying child support which he has no problem doing and I'm happy as long as we get to see him because we haven't since the mom found out I was pregnant and is spiteful, but it will take a large chunk out of our savings for a home. I'm due in 10 weeks, then I'm going to school for dental assisting so hopefully we will have a place by the time I'm done with school so we can be a family together. My dad has a 3 bedroom house just big enough for him, my brother, my baby and I, and now my sister and her bf broke up that was supposed to be throwing my baby shower so I don't get one, and she's trying to move back into my dads. She's 24, won't get a job or go to school, is on methadone, and will smoke in the house even if we ask her not to and try to get the room that is big enough for both my baby and I to stay in because she's the oldest and deserves it. I'm just lost right now. I need prayers and uplifting words and hope because I feel like I am loosing everything.
