I put my mom on Linux Mint Cinnamon (Ubuntu based) looks a lot like windows with minimal bells and whistles. Mostly just works unless you have bleeding edge hardware. Most Ubuntu flavours should also work. I’m suggesting Ubuntu based distros due to the fact that most media codecs, fonts and drivers are installed or easy to install.

Whatever I feel like. I wouldn’t decide on a whim but consider my feelings properly. Forgiveness is not a rational thing IMHO. Edit: typo

I’m not saying this is the best advice, but maybe it resonates with you. Find a non fictional character or any subject that seems interesting. If there is a person that seems cool and has a biography try reading/listening/watching that. By doing this you broaden you horizon a little and that itself should give you a slightly changed view on your own fictional character. In this way you and you character can evolve together and that may also change your relationship with the character. As others have mentioned, joining a group activities like sports, volunteering, debating club, etc can also be beneficial. TLDR: Broaden your horizons. Try to interact with new people and new ideas/views.
