Why do a healing phase have to be lonely?

HEAL AROUND OTHERS

So, I get hurt by something or someone but in order for me to get past it I must ponder in my own thoughts? In order for me to not react crazy I must sit and watch what I say at the situation or to the person, why is it that people are required to heal solo? I see it as this way we have family and friends for a reason why not just find people or things other than hobbies to have for that moral support or that comfort.
