What is it that you're dreading about the things in your list?
Based on my experience only (obv everyone is different, 2 births, both gas & air, one induction):
waters breaking - this doesn't hurt. It's a weird popping sensation, and then obv waters...
contractions - yes, it's going to hurt, but you get a break between contractions and they don't hurt like hell for the whole contraction, and they tend to build up quite slowly at first. Gas & air really helped me deal with them, possibly mainly placebo as you've at least got something to do during them, not sure.
crowning - not going to lie. This is fucking sore, but it's also the absolutely last bit and means that you're about to finish the whole thing. Nothing like as sore as running a marathon imo! You also are pretty much pain free after the baby is born. It's like some miracle 
needing induced - results may vary, but my induction was a piece of piss. It can work out well. With ds2 I was resigned to being induced but went into labour naturally the night before, so it's not a done deal until it happens anyway.
tomorrow's sweep - you don't have to have one if you don't want to. There is pretty much no evidence that they work.
not being able to have the water birth I so badly want - sorry, I didn't get this either as the pool was in use both times. Still had 2 good births though.
the pain in general - it usually builds up. You're not in pain for the whole time.
c-section if needed - no experience, but know lots of people who had a good c-section.
being alone in hospital (I may work in one, but I am the world's worst patient if I am alone. Hubby can stay if I get a home from home suite but if I need induced then that can't happen) - hopefully you will get discharged quickly, potentially within 12 hours if all is well. I found things much easier to manage at home with dh's support.
the aftermath - well yes, the birth is just the start and postnatal stuff can be hard. Having a newborn is amazing though. Just Amazing. Take help where you can get it, tell people if you're finding it tough, don't suffer in silence because you think you should be coping.
