Hi J.,
You are experiencing exactly what I fear I will experience next year! I think it's pretty common from what all of my working friends tell me. Some suggestions that I've gathered from them:
Use Peapod for grocery delivery.
Hire a cleaning lady so you don't spend your weekends cleaning. (Decide what you can afford...even once a month is helpful!)
Put as many of your bills on auto-pay (through your credit card/checking account) as you can
I know that doesn't solve everything, but I thought those 3 things were at least a start.
Hang in there...I think it's so hard because as moms and professionals we see so much that needs to be done...and we sitll need to remember to find something that we enjoy in addition to loving our children and our husbands.
On a positive note it sounds like you really love your job and that's a huge plus. Have you considered moving closer in to the city? It sounds like it might be time to at least give it a second thought.
Good luck! :)
