If you have strength of character, you can use that as fuel to not only be a survivor but to transcend simply being a survivor, use an internal alchemy to turn something rotten and horrible into gold.
If you want to do something healthy for yourself - focus on your internal relationship. A diet, external, or materialistic fix WON'T work.
The best piece of life's magnificence is your slice of internal peace.
Only internal bliss is perpetual, nothing else is created to last
