I'm the sort of person who prefers to swiftly deal with problems before they become a big deal and not take any chances so I avoid unstable or problematic people from the get go. Nobody is perfect and we all have our issues and flaws, but if you're unstable and I don't consider you a friend or care about you beyond surface level, I'd rather you go your way and I'll go mine. I know it may seem cold but I don't have the time or energy to deal with people like that. I go the extra mile to support the people I care about but everyone else can fuck off.
