Under severe stress they become temper tantrum children. The ones that haven't have never been put through extreme stress. They will begin to resort to consuming or using more nicotine/alcohol/weed/anything to put off emotional aspects of themselves until it becomes bad and they either disconnect and become icy cold or have a breakdown because of bottling in emotion. They have a tendency to act so distant that at times they hurt themselves by hurting someone else by distance which makes them withdraw further. If they are unhealthy they will become a chaotic chameleon (if they're healthy I'll call it a chamomile chameleon) and come off as extroverted, cocky, toxic levels of pessimism, argumentative. Side note: These are INTP behaviors when they've had too much stress and do not have the living arrangements to isolate/retreat. If they cannot find a place for clarity & calm they become confused and angry very fast.
