Q. I always wonder if it's better to give people space or to involve myself in their troubles. What's best for each individual is different, depending upon that person's personality. Whenever in doubt as to what you should do, you can always ask the person in need. Simply offer to be there for him or her. That offer itself is a great comfort in troubled times.
Some people seem to swallow their feelings in a time of trauma.
Others get angry, even with those who had nothing to do with their trouble. Those who turn their pain inward are more prone to depression. Those who turn their pain outward often lash out at others. The behaviors you've noticed are the expression of different coping styles. They are probably rooted in basic personality, which is an area full of mystery, even for experts.
