Being a survivor doesn't mean being strong - it's telling people when you need a meal or a ride, company, whatever. It's paying attention to heart wisdom, feelings, not living a role, but having a unique, authentic life, having something to contribute, finding time to love and laugh. All these things are qualities of survivors.
When my body gets to the point where I can no longer function or feel gratitude, then I'll leave it and become grateful again. But until then, I will appreciate what I have and not whine about what I don't have. I will feel blessed by life and the opportunity to help others see that they are blessed, too.
You can survive tough situations and even turn them to your advantage by acting as if you are the person you want to be. When you act like that person, you can become that person. The hard parts are deciding whom you want to become, being willing to rehearse until you become that person, and forgiving yourself until you do.
