Your son's "Indirect Resource" star is too strong. He gets better after 22. There are a lot of things he could change, for the better. However, according to his chart you may not be the best person to influence him to make these changes.
Besides finding professional help, for now, you can try suggesting for him to sleep in the NE room for this year. Hopefully the positive star in that room would give him some stability and clarity in his life.
Warm Regards, JY
