I need sleep!

Help! I am home alone with my 10 month old, trying to get him to sleep. Hes woken up about 8 times in the last 4 hours, he wont stop tossing and turning and waking up screaming. I'm getting so upset and trying to stay calm. My husband works nights so I'm the only one with my son all night long every night. I'm so tired, I can't get him to stay asleep, I need a break and there's no one here to help. I have never felt myself get this angry at him when he wont sleep. What do I do? I'm almost to the point of putting him in the crib and shutting the door and just letting him cry, which I've never done since his crib is still in our room. But I'm almost to the point of sleeping on the couch and just letting him cry himself to sleep. I can't keep doing this. It feels so wrong to be angry at a baby, but I am, I'm so angry.
