i need help..

i have HORRIBLE morning sickness, like i have already lost so much weight, i can’t eat or drink anything.. i’m considering an abortion.. me and the baby’s dad just got pregnant after a few months of fooling around. yes it’s my fault, i know that. i already have a one year old. i don’t think i can do this.. i don’t know what to do. i’m gonna be on bed rest from 10weeks to until i give birth, with injections every other day or week. i’m honestly just so down and feel so weak. i don’t think i can do this.. i feel so helpless, zofran isn’t working, or barley working when it wants to. my daughters dad isn’t in her life so i’m a single mom raising a one year old. i can easily miscarry, i have an incompetent cervix. i’m just so lost right now.. any advice?
