Is there any good way to deal with negative kin memories andor feelings?

I find it best to deal with negative kin memories and feelings the same way I deal with negative memories and feelings in this life. Accept that they happened, and you can’t change them. Its okay to be sad and upset, but don’t let it take over your life. You can distract yourself with things that aren’t related to your kinself/canon, and you can treat yourself and indulge in things that make you happy.
