Giving birth alone..

I rather not explain why, but I will be giving birth alone (this will be my third time in 3 years) in less than 3 months and just wanted to know if anyone else has experienced this?

Both other times I had at least a support person, and my mother to call or FaceTime. I have nothing, not my kids father, not my "sister" .. not my mom.. she passed away 3 months ago... I'm terrified and embarrassed already
