Priorities

Without delving into my personal life too much I'd like to reflect on priorities just a bit.

With so many things on my list of priorities, how should I differentiate between the true and the pseudo priorities? Everything seems to be a priority nowadays and I can't help but feel completely overstretched and overwhelmed.
1. My son
2. My husband
3. My house (and cars and other things that need maintenance and such)
4. My work
5. My family and friends
6. My wedding
7. Any other thing
8. Me
How do I balance trying to keep a happy, healthy relationship with my husband while caring for my son and cleaning the house, organizing the house, getting rid of clutter (thus making it more childproof, too), working as much as possible while my account keeps going lower and lower, scheduling with my friends and family, going to venues, meeting vendors, making decisions (not a strong suit of mine), and doing other things as needed? Oh, it'd be nice if I were able to take care of myself, too.

The trigger? I broke my breastpump and now I'm unable to pump and yes it is almost 3AM now. Sorry for the run-ons but I figure 3AM is ok for verbal (or typed, in this case) diarrhea. I looked up the nicest one (since I figure I'll hold onto it for the next child in four years) and it is over 300 dollars! Close to 4. So now the stress of money and time are playing against me and I need to make a decision (which basically I have done already). I'm going to Target when they open (in about five hours) and just bite the bullet and buy one. If I can, I'll get a replacement part for the one I broke and then I might even have the luxury of having two pumps (I do hate bringing one back and forth from work to home to other places as needed.

As for the list of priorities, I'll be sure to post again. If I figure anything out, I'll share my wisdom. Until then, I'll just bring up questions.
