In this situation I would take him into bed with you and offer him unlimited access to the boob. You may not want to co-sleep long term but in the short term it will get you a few nights sleep and some clarity before you think of the next steps you can take to help him sleep. He is of the age where he may get distressed if you are away from him, so a few nights of constant cuddles may just be the key to relaxing him.

Good luck with this. I have been there and it is so tiring. Please don't be upset with yourself for shouting at him though, it is a normal reaction when you are very tired and most mums have done it as some point.
