Anyone understand?

I am 34 weeks pregnant and working 45+ hours a week. Me and my husband both very recently turned 18 and live with my parents, but We do pay them $400 a month rent. We also pay around $350 on my car for insurance $90 on his car insurance, $400 on my car payment and $180 on my phone payment. Plus I am making sure I have everything I need for my baby and paying my own medical expenses. My husband works as well. We also pick up things from the store when needed and help out in any way possible. I had an emergency hospital visit today to check on the baby due to a fluid leakage, now we have to worry about that bill as well. We do chores around the house to help out. My 17 year old sister who only pays $60 of car insurance, and never does any chores at all just told me that if she were my parents she would kick me out and that she was going to have a talk with our mom about me. All because we bought a car seat today and had the box in the hall until my husband got home from picking up my medicine from the store. I’m just crying my eyes out because I try so hard and our money is already so tight. We have looked into apartments several times and it’s just not an option for us right now. My husband and me were talking and we think the only thing we can do is for him to get a second job on top of his full time job so we can move out. And I know what everyone is thinking. We do need to move out because we are adults and it’s part of it. But we were only staying because my parents thought saving a little bit that would have gone to bills would help with my maternity leave. But now that has to go to a rent deposit 😭. My sister gets at me almost every day and I can’t take it. Our only choice now is to move
