Confrontation Issues

I'd like to deal with my confrontation issues, but the problem is that there actually can be legitimate reasons not to confront people about things, it's just that there's also a lot of bad reasons not to lol and sifting through all that is a mess.  And like, if I were better at doing it I could hope for better outcomes but I'm actually really bad at it (unsurprisingly) and I don't relish the idea of destroying all my personal relationships in the process of trying to get better at that.  At the same time I feel that not trying to improve in that area is simply intolerable so I really do have to do something.
