Yeah I'm also one of the "givers" and it does get away with me every once in awhile. I try to set limits, but it usually happens after I'm pretty tired after being supportive to so many folks. My threshold is about three weeks, then I start feeling ill, so I make sure I get time to myself about every two weeks or so to recharge. I also have a pretty good network of supportive girlfriends who are ready to listen and let me know that I'm an okay person, so I'm pretty lucky on that front.
