Write your obituary. Not as it would be NOW, but as it would be at the age of 100. Write out who you are, how you want to be remembered- but include that recovery you're working on now. Write about how you never gave up, and make it positive, include the POSITIVE outcomes you're working towards. Include every good quality you have and those you're working on. Keep it realistic in terms of goals- wrote a book, worked on quilts, whatever, but include things you do, done over many many years.

This helps a little. Not a lot, but a little. And yeah, even normal healthy people have this fantasy, even the part about dying in an accident or of some rare disease. We all want to feel valued.
