Anxiety is on 10 all the time

I have 3 weeks left before my scheduled c section and I don’t know if I will have anyone to help me with baby in the hospital the dad is very unreliable and stopped showing any interest after he left me n got a new girlfriend a month ago and my mom has addiction issues that effect our relationship and she was trying to get me to have an abortion even past 6months. So I’m just really feeling like I have no support system I feel like crying every time my doctor brings it up because I know I’m going to be doing this all on my own and with my first I had an emergency c section and I had his dad there being very helpful even with my needs and I just know this time will be nothing like that I’m excited to meet my baby but I feel so bad for bringing him in to all of this I’m scared to be by myself cut in half with a newborn the only thing I have ready for baby is clothes got washed I did buy a bassinet I just have to put up but I still have no car seat stroller or a swing for the baby and I didn’t have a baby shower cause I don’t really have friends or family so I need to figure out how I’m gonna get all that together on my own before he’s here I’m still working but I’m self employed and business is so slow right now. I’m really struggling with getting myself out of this funk I don’t feel bad for myself and I just wanna grow from this and handle everything but it’s so hard I can’t control my emotions I feel so bad for always crying infront of my little one he’s never seen me that way until I got pregnant I’m so blessed with this baby arriving soon I’m just totally unprepared I’m a wreck
