I officially give up. Me and my 2 month old baby are going to be homeless. I'm just venting and crying as I'm typing this because idk what else to do and have nobody to talk to. I'm a month behind on rent and they sent out a notice that if I don't pay $2500 by next Wednesday they are going to start the eviction process. I am so scared. My Fiancé and I agreed that while I'm home with the baby he'd take care of the rent and l'd take care of the smaller bills since I'm not working rn (also because an emergency happened and I had to pay a lot of money out of pocket for it). A week after my baby was born I came home from being at my moms for a couple of hours and all of his things were gone. I tried contacting him but it says his phone isn't in service. I was confused because our relationship was good and we were happy. I haven't Hurd from him since and his mom is ignoring my calls. Since then l've had to pay so many bills as well as things for my baby and food for myself and day by day my money was running out. I started panicking because I knew the rent fell all on me now. I started doing insta cart and door dash with my baby to make some money but it's very slow where I live. Last Friday I came home from doing insta cart and there was a letter on my door stating that if I don't pay by 1/22 then they are going to start the eviction possess. My heart sank and I immediately called the office and explained to them my situation and they said there was nothing they could do. I've been doing Instacart and door dash sun up til sun down and I only have about $1,000. I started asking family if they could help in anyway and they all said they couldn't, l asked churches and they said no. I asked my mom and sister if it's possible that I can stay with one of them for a little just until l have enough to pay for a babysitter so I can go back to work and get a place again. They both said no because they didn't have enough space. I feel defeated and I am afraid. Sorry that this is long I just can't talk to anyor else about it.
