Canceling baby shower because emotional...

I am extremly emotional and my baby shower would be april 25th and I feel like shit. I dont have much family here and my sister and mom said they would help with the baby shower if I payed for everything. At first I was excited because this would be my last kid and with my other two I didnt have a baby shower. Now I just want to back up and not do anything at all I feel like no one is even gonna show up, Im gonna spend too much money that I could just use for the baby, the dad and I are together but most of the time I feel so lonely and with no help like he dosent care about his baby and early on the pregnancy he made a comment about how it was the worst time to have a baby he didnt even want to go to the baby shower. Idk if its the hormones or Im just done with everyone and everything. Ugh. Rant over since I have no friends and no one to talk to
