Working, taking care of the kids, the husband and the house leaves you very little time to take care of yourself.
You're adjusting your life to everyone else's needs. No wonder you feel like you need to escape!
On top of that-with what Parker said- it's not helping the situation at all.
Woman- you need a break! Not like a run away break- more like a VACATION away from the house,kids, husband and job. Yeah?
Yep,Yep!
Okay, you can't get away for a week or so-by yourself? Not do-able, right? What about a time slot every week? Like a two hour "MY TIME" thing? Is that do-able?
OR!!! GO get yourself a weekly theraputic massage!

If you can't afford a weekly then get it once a month. But it's gotta be for the full hour or even an hour and a half! It'll work wonders on your poor tired soul.
That's the best advice I can come up with.
