Deflated

I’m 37 weeks tomorrow with my 2nd baby (first one is 2 and full of beans) and I just feel done. I’m having a c section at 39 weeks for health reasons and yes I know it’s only two weeks away just I can’t help but feel deflated. I hate moaning because there are people that struggle to have kids and can’t and I know I am lucky I just keep reminding myself. I was in hospital with chest pains two weeks ago and last week with cramps. (Both unrelated to pregnancy) I barely leave my flat expect for when my partner is home and I constantly feel guilty for my daughter am I doing enough with her? ( she goes nursery two days a week) I feel so sad it’s not gonna be just us three anymore is she going to hate me? Every cramp I have I’m like omg is it time then it all goes and it so tiring! I haven’t slept properly for months just want to skip first couple months is that bad? Anyone just feel done? Physically and mentally?
