38+5 c section and lack of sleep

I'm almost to my c section date. I havnt been sleeping well. I know most of it is because I can't get comfortable and my SO has been taking up the whole bed and I can't breath laying down and all the heart burn and itching I give up and just lay on the couch on this app all night...yay. but it's been worse the closer I get to my surgery...it's really starting to bother me. This is our first together and his ex had a c section but I'm worried he won't be understanding that I'm having major surgery and expect me to be able to do everything...also the surgery itself is freaking me out its my 3rd and they get harder to perform and riskier to do. I'm just over tired and stressing myself...well good thing he's got to go to work in a hour and I'll get the bed back. Wednesday earlier Morning I'll be getting prepared for surgery with the nasty drink so you don't puke and hoping my spinal dosn't take forever with my scoliosis but I'm sure it will and soon after 930 am I'll be holding my baby final. ..it's the only thing that helps is the outcome of it all being able to see and hold this baby for the first time.
