Sleep training?

So I think the only thing this is training is me to not sleep. We got the going to bed thing down no problem. I can do all her nighttime rituals and then lay her down awake or drowsy and she goes to sleep on her own. I can also do this for her naps. The only problem is that she doesn't nap long enough. She wakes up after 45 minutes to an hour. This I don't know how to correct. We are also trying to have her not get up to eat except for once during the night. She has been going to bed at 8 and waking up starting at 10. I can then feed her to sleep and she is up every hour on the hour. I decided that she didn't need to eat that much and I needed sleep. We decided that we would just go in and comfort her but not pick her up. It seems that this just makes her cry harder. I have had 11 hours sleep in the past 72 and can't do it anymore. I almost left last night. I don't know where I would have gone but I wanted to leave and sleep and not listen to her. I have had a fussy crying baby for over a week now and I can't deal anymore. I need her to learn to take a bottle or something so I can go out by myself to do something and have a break for more than an hour. Going out to get groceries doesn't count. I need some me time I have decided although without sleep I can't do anything. Last night was the worst. She woke up at 10 and screamed till after 2:30 at which time I gave in and fed her cause I needed some sleep. She fell asleep and slept for an hour then screamed till 7 then I fed her again and she slept till 9. I know she needs better naps but I can't figure out how to make her sleep longer. I also don't know why she is waking so early now and wanting to suck constantly. I just don't know what else to try so that I can sleep
