i can understand why you are so very concerned. it sounds as tho his mental state is very fragile but i am not a professional. if he were my son, i'd print out what you wrote here, schedule an appt. for yourself with a mental health professional, psychiatrist or psychologist, and take this post to the appt. it's well written, explains his behaviors. this assures you won't forget anything at the appt. they can i'm sure offer you wise guidance re your son and perhaps offer helpful suggestions to help your son. i wish you the very best-our sons are so dear to us.
we are a very supportive community and i hope we can offer you all the support we can offer to you in these difficult times. please keep us posted. we care.
