In less than an hour I'm meeting with my sister (and my mom) to tell her that I can't watch her kids anymore. I gave my mom a heads up last night. I know my sister is going to be disappointed, but I hope we can just brainstorm ideas together and come up with alternative plans without laying too much additional stress on her.
To say I'm apprehensive does not even begin to cover it, but I've been feeling such a sense of relief about this decision I know it's right.
Now if we could only figure out how exactly we're going to pay all the bills each month without this additional income . . .
