Nightmares vbac and c section help!

My c section three years ago wasn't good. My son was 9lbs and he was so stuck the doctor was shaking and had to switch out nurses and use three forceps and kept going back to the kiwi. Finally he got out. My dr said most 9lbs babies are easy to deliver. I am a small person. Before my first son i was 96lbs and I'm still 5'1. I'm currently sitting at 119 lbs with this pregnancy start out weight for this pregnancy was 106lbs. My first son was from a different man( he could care less about his son) my sons sperm donor weighed almost 9lbs and ripped his mama bad. Now, this go around my husband he weighed only 7lbs 1oz!! Will this make any difference? I keep dreaming awful dreams :( I can't sleep because I've got restless leg syndrome. I woke up this morning with both legs hurting and I'm currently at work and can barley stand without my legs and back killing me..
