post-traumatic stress disorder at 6months

I am 6 months pregnant and I think I’m gettin ptsd.. my boyfriend went to jail when I was only 14

weeks pregnant and we just moved in out 2 bed room apartment our first one at that .. I wasn’t working he was the only one with the job pretty decent job so he told me I can only go to school I didn’t have to work .. but I ended up gettin a job 3 days after he got arrested ... lucky for that I got to pay off November rent and December rent .. I paid off January rent thankfully but my job is cutting hour real bad and only have me working 1 day ONE DAY ?! Like how is that gonna pay all my bills and I have a car ! It’s gettin so stressful for me .. I fill out applications after applications but when I call jobs back their either full or tell me they will call me back .. I’m trying so hard but it’s like I’m always failing .. I dropped out of school just so I can get a full time job ... I tired to talk to my mom but she tells me I have issues and she don’t want to hear all my crying ... it’s to the point where I cry nonstop everyday I make myself sick and I try to stop cux I don’t wanna stress my sweet son but it’s just so freaking hard !!! Im only 20 years old my life changed so fast .. it went from me being a school girl living with my mom to me about to become a mom and taking care of bills and home . This is not life .. and I’m just afraid I’m not gonna be a good mama to my son !! Don’t get me wrong I can’t wait until my baby boy gets here but doing it all by myself is sooooooo scary !! I’m due I’m 3 months and I only have 2 outfits for my baby !! And I don’t even have enough money for a baby shower .. guys I’m sooo scared .. I made an appt with the therapist becuz I’m having really bad thoughts and this is not me .. I’m normally happy bubbly and make people laugh non stop .. I hate my boyfriend for leaving us like this !!! I really do !! Can I have some advice please ?
