I would also like an answer.
The only one I’ve thought of is to change to a constitutional monarchy like the UK and put me in charge. (Obviously, it would be me because I am the one waving the wand.) The king would have absolute power to resolve constitutional crises, and would otherwise just have a ceremonial role.
You say you have mental illness. That might be so, I don’t know. But I will say that everybody, even people without mental illness, make mistakes like you described, especially at your age.
Everybody has dark and light inside of them. Being aware of this and being concerned when you make mistakes is usually a good sign that you’re not a bad person. Try not to compare yourself to other people. Compare yourself to your past self. Keep improving and try to make fewer mistakes. But don’t punish yourself too severely for making mistakes. Just keep trying to do better.
