Hi dionna!
As I read your post it felt like I had written it myself! I can TOTALLY relate to what you said! My guess about the gaining of the weight without seeming to realize it is that we get so busy with our families, our jobs, our husband, our children, our house etc. that we really do place ourselves on the back burner! We stop thinking about ourselves and do everything for everyone else. We work on becoming the best wife, the best mom, the best daughter, the best (fill in job title here), the best granddaughter...The list goes on and on. What we have forgotten is to put OURSELVES into the list!
I spent thirty years worrying about everything EXCEPT myself. At one point I was sleeping just three or four hours a night and working two jobs so that I could spend all my "extra" time helping everyone else to have a wonderful life. Their lives WERE wonderful, but I was ready to collapse! I really needed a life adjustment!
Seven years ago I decided that since my sons were getting older (high school and college age), that it was finally time for ME! I quit one of my jobs, started walking, started watching what I ate, and reclaimed ME! The crazy thing about it is that everyone seemed to do just fine without me doing all the extra stuff for them! Things went on just great! I began to realize how utterly STUPID I had been to try to be eyerything to everyone!
I am a changed person now. I stand up for myself, and people respect me for it. If I need something, I ASK for it instead of feeling sorry that my husband and sons don't just KNOW that I need it. It has taken me 55 years, but I think I finally have learned how to live in my world without being everything to everyone. It feels very freeing and very, very good!
Good luck on YOUR journey! Try not to fall into the same pit that I did!

It is hard climbing out once you fall in!!!
