Hello,
I can only speak from personal experience, but I have found that encouraging others to refrain from interacting with these unhealed folks as often as possible is the best way. But since we live in a society where these people run rampant, cultivating a foundation of self-mastery where you take the time to know yourself inside and out is key.
Leading others to a path of self-mastery, along with the acknowledgement that they are special and here for a reason that expands beyond the limitations people try to give them, can help one break free.
Magick is the process of manipulation, and nobody can manipulate you if you know yourself better than they think they know you.
I hope this helps.
