Maintaining self while taking new roles

Has anyone else found it hard to balance self care while taking on this new role? I am a new dad with a lot to take on all at once. When we found out we were expecting, we discussed childcare, job opportunities, etc. It worked out better financially for me to stay home while she worked. Needless to say, I was poorly prepared for the all consuming task that is raising a newborn. I have him from 5am until 6 pm daily. This leaves about 2 hours a night which I spend washing bottles, making dinner, catching up on chores and occasionally running an errand or two. I feel like I get almost no time for my health or wellness. And to top if off, now I have zero income so I'm too broke to do anything other than stay at home anyway. I want to work part time but that would take what little time I have with my spouse away completely. Any suggestions, experience or tips?
