I'm sorry to hear about your son, so very young to experience such a life changing event. Working Corrections is a dangerous job to mind, body and soul. Someday he will achieve balance again, not the same as before, but none the less a sense of peace. The struggles will of course will remain, as I am reminded each day. I have far to go yet, progress is measured in tiny increments.
The meds...often enough, several will need to be tried, dosage is critical, a balance between enough and too much can be tough to find. God speed.
