I've been here for two days, here's some background check..

I felt like me and my son needed a new start, to try be independent, get our own place, I got a job, but didn't have nowhere to stay to go to work, my mom said I can crash on her couch for a few days and so I sent my son to his dad's who just lives up the street from her, (he insisted we get back together and raise these babies together but after cheating on me and getting drunk and hurting me I don't think so) so I denied his offer and continued on with things, was working for a few days made some money, and was also looking at a few places, then my mom told me I had to go because her roommate was getting annoyed of my being there so I ended staying with my son's dad, but things were not going well, he kept tryna talk about us, kept being to nice and then complaining that I take his niceness for granted, so I took my son and went to a shelter but still no child care in there for my shifts, also his dad wouldn't let me take most of our stuff, but they said they would watch him while I work.. so I agreed, finally came down to being accepted for a viewing, I went.. I didn't get too see much I didn't know what to ask, he said it was being renovated, so it smelt like bad chemicals, (I'm 27weeks pregnant) but it was affordable, and doable for my pregnant self and I could just walk up the road to visit my son, so I put down 500$ for a DD, and was told I could move in now, I went to take a look at the place again, the room was small, still smelt like chemicals, the windows couldn't open, and the roommates looked like they were on drugs, so I asked for my DD back because I was gonna stay there and be pregnant, but he said no I couldn't get it back because I wasted his time and made him turn down two other people who really wanted it.. so I lost alot of money, tried to go back to the shelter but they said I'm never there so they gave my room out to someone else, went to my mom's and they were all leaving for work and asked me to leave too, walked around town for awhile trying to think and crying my eyes out because I broke, pregnant and nowhere to go, the last place I wanted to be was with my ex, but he just kept insisting and saying we will change, and I said no no no no!!!!!! He bagged up all my clothing and belongings and had left the on the road with me.. and started saying looks like it's just gonna be him and our son for the ret of their lives, blocked me on everytging.. but I don't blame him.. so there I sat in the bar, crying unsure what to do feeling like a burden, like I'll never see my baby again.. I'll never provide for my unborn child, I contemplated suicide.. I still am is why I'm in the mental health unit, but they only come in to bring food and ask if I need nothing, nobody has actually spoken to me yet in two days about what has been happening.. so I'm gonna discharge myself and leave . Idk where I'll end up I just don't know what to do at this point.. it's always just been me and my son since I was pregnant and since he was born, and coming back to this town has ruined everything . Everyone is cruel. I don't wanna leave my baby but idk where to go with him.. I'm just so upset right now that I lost all that money that could've gotten us a hotel for awhile instead..
