Help please

I am 19 and 38 weeks pregnant and I am cramping like crazy my back is killing me and I am fighting tears. I want my mom so bad. I dont understand what is happening I know my baby is coming but I am so scared. I want her to come and hug me to make all the pain go away. But she is across the country and just told me that she wont be coming to the birth. I thought I would be ok but I am not I am so scared. This hurts so bad and I feel like I am going to explode. 😭😭😭😭 I dont know if I can do this. I mean i know i dont have the choice but i dont want to. I wish there was a fast forward button so I can skip this part.
