Broken people feel others' pain most acutely. We learn to look away, or to devote ourselves to making things perfect. Neither technique works very well. Do the former too much, and you remain an outsider, sternly acting with indifference because you know that getting involved just opens up too many scars. But do the latter, and you empty your life and time completely into someone else. And most of those "someone else's" don't understand the attention, don't want help, and eventually run away. There is no solution. Just find some pretty things to distract yourself in life, and take up some hobbies. There is no undoing the damage.
