Should I keep a "diary' of what I eat, feel, do, crave, etc?

Sometimes, I crave sweets really bad....sometimes, I can't be satisfied no matter what I eat.

It's not really that I eat that much either...I have friends who eat much more than I do, and never gain an ounce. I remember when I was a size 10, I kept telling myselff and thinking that I was too fat. I was the smallest one in my family and now I am the biggest. My father who will be 89 soon, is in excellent health and has never had a weight problem, but his mother weighed about 500-600 lbs before she died. He had neices and nephews who were terribly obese. My mother gained weight after her 5th child got many health problems and was on dozens of prescriptive drugs before she dies at the age of 68, she had lost her weifht tho and was on a diabetic diet for her diabetes. I think growing up with the fear of getting fat......then seeing what drugs did to my mother made me afraid may have ssomething to do with my problem. Now that I look back on it. I do know God will heal me, and I know He will send the right person or information that I need. He knows my heart.

Thank you ALL who have taken the time to assist me with this.
