I don't want to try prolong my life with chemo.
Is there something about chemo that you don't like?
I hate my life, and I'm tired of chemo, and I just want it to end.
If you don't want to do chemo anymore that's understandable but wanting it to all end isn't okay. You should try to cherish life and the time you have left.
Given what's happening now, I wish I had just died in high school so that I could have avoided all those embarrassing moments.
It's completely understandable to feel frustrated about the past, especially given your medical diagnosis. Instead of focusing on the negative moments of your past though, try to think of the happy times! I'm sure you had plenty of good memories with friends and families.
