Triple me

So there seriously needs to be like at least two or three more of me to go around!! When you really stop and think what your doing as a stay at home mom it's crazy, your doing multiple jobs!! We cook, clean, drive kids around, teach, play nurse to the sick, run the home, balance your family schedules and really the list could go on and on. I feel like I need a assistant to help me out, the only problem is...I'm not get paying a dime!! I feel pulled in so many directions, my attention and time being pulled between my children, husband and duties...when am I suppose to find time for myself?? I have a very long list of things I need to do, and a even longer list of things I want to do. I get things checked of the "need to do" list, but I feel like I'm never able to check things off of my "want to do" list. I'm not sure I know how to balance my life in a way that is productive and healthy. I think I spend too much time giving, actually I spend all my time giving :) This is something I need to figure out/work at, finding a healthy balance. So my question is HOW??
