I'm pregnant with twins and a 9 month old baby on my own

Hey, My name is Haleigh. I’ve never done anything like this before but my friend suggested that I could try to see how this works. I’m 19 years old and I have a beautiful 9 month old daughter. I am also 20 weeks pregnant with twin boys. I’m unable to work a job outside of the house because of the babies. I’m applying for some at home stuff but nothing has gone through yet. I’m still waiting to hear back for some interviews. As of right now I’m staying in a small apartment with my 2 of my friends, who also have 2 other roommates so total there are 6 of us staying here in a two bedroom. It’s really cramped and I’m waitlisted to get my own apartment that I can try to afford. I’m beyond grateful that my friends are helping me out, I just wish I could have some privacy and my own place. When I was 7 years old I was put into the foster care system. My parents were both drug addicts and couldn’t take care of me. So the state took me away. I battled with foster care until I was 18. I want my kids to have a normal life. I would suffocate if any of my baby’s were taken from me they are my life and without them I have nothing, I was meant to be a mom. Maybe not this soon but it happened and I wouldn’t change it for the world. These children deserve an amazing life as all children do. I recently also acquired my GED! My next step is to get into college. I will provide for my children. As for the baby’s father. He is still around he is trying to become a rapper. He goes to concerts a lot to perform. He won’t man up and get a real job in the time being. I have had to sell most of my clothes so that I can give my baby diapers and wipes. Just today, his grandma gave him money to go do whatever he wanted with. So he bought himself an entire new outfit and two new hats. He knows that I have been wearing the same bra for 2 years and he knows I only have 2 diapers left.  He doesn’t care about my physical situation because he is too worried about his own life and his own success, I know he is cheating on me. I feel so stuck because I don’t feel its right to leave him. I know he has potential to be an amazing guy and father. He just needs to grow up and how am I supposed to leave the person who I have 3 kids with now? This situation is even harder because a few months ago we had everything, we had our own place and everything was fitting into place. And now I feel I have nothing. I don’t have a home, I can’t afford my babies diapers, I don’t have the money to take her to a daycare or babysitter so that I can work during my pregnancy either. Everything fell apart this year. I just really need some help getting back on my feet. I never thought I would be on here asking for money but if anyone feels generous I would greatly appreciate it. I want to get back on my feet and get ahead, if only I can quit getting knocked down. Thank you so much for reading my story xoxo Haleigh
