Absolutely. Yes. Yes, yes, yes, and more yes. Actually, no. If I could change anything in my life, it would be that my parents never got together so I'd never be born.
I've never been a healthy kid, and my family stops at nothing to let me know that taking care of a disabled person is a drain on time, money, resources and emotional involvement, so in order to keep my family from being burdened, I'd like to erase myself. Too bad I have no time machine and this is just an intellectual concept.
Edit: But besides that, a few things I'd change:
1. Go to the police about certain things when I was a kid instead of thinking it was how all adults are
2. Make sure I got to my friend Mike's funeral
3. Make sure I kept contact with my friend Stephen after he moves, so when he gets murdered, I have the info I need to go to his funeral
4. Make sure that the last time I saw Stephen, no matter how tired I was from a 16 hour shift, make time to talk to him one last time
5. Not kick my dog that one time that I still regret
6. Go to the police and hope that my friend Normand doesn't die because his situation is known
7. When my parents got divorced, side with my dad regardless of my mom's brainwashing
8. Never go to college
9. Never go to washington (the state)
10. Never go to any of the things that made me into an imaginative person
11. Become a drug addict
12. Instead of saving myself for marriage, be with every girl who offered
