Be careful not to do too much for others or you'll neglect yourself and feel bad about it later. Of course, no one is going to fully appreciate all you do for them -- it's just human nature to take others for granted.
I notice "people pleasers" and "do-gooders" often in my spiritual weight loss workshops and seminars. Care-givers somehow often have weight problems. It's a common pattern, and I’m not totally sure why. I was one, also. I was always thinking of how I could please my parents, teachers, and friends while putting my own needs aside. For most of my childhood and teenage years I cared for everyone around me, while feeling awful inside and overeating to compensate for it. I had to learn how to take care of myself by eating in balance and moderation. I learned to care for my body, enjoy exercise, free my mind and intellect, and express my emotions. I simply had to become my own advocate and state my needs and ideas. It was difficult at first, but it really has helped in the long run.
Truth is, no one is going to take care of you better than you can yourself. So take some of that energy you spend on others, and think about ways to please yourself. Try asking someone for help. State your feelings and needs in a gentle, kind way.
Every day, take at least a half hour or hour to rest and recharge. Go to a movie or concert, take a nice quiet walk in a nearby park, soak in a hot bubble bath, or read a book or newspaper.
