I want to say something supportive. I'm not sure if this will be supportive or not.
I am 62 years old and have some health issues. I sit here and kick my own ***** that I didn't do this or that...that now I can't go here or there on my own.
Then I read that you are giving all that away...all those chances for fun and fulfilling experiences.
I know you are hurting. I used to SI, too.
My wish for you is healing for the *real* hole in your heart

so you have some time left to go to water parks, take in some roller coasters, go to the beach and breathe sea air, visit DisneyWorld (or some awesome place) because I will never be able to do those things again, myself.
Reading what you are doing- I just feel so sad for you.
I wish you the best. We all deserve the best.
