Am I ready for a 2nd baby?

With our first baby, my husband wasn't quite there for me emotionally and physically. We have a 2 year old boy, and we both want a 2nd child. But I don't know if I can physically do it all over again by myself. Getting up all night with a new baby and with our son also. Please, I need advice. If any other women have done it all with 2 kids being that close in age. Thanks.
