From last 4-5 months keep on thinking very deeply, no social touch, not interested for any work, cannabis addiction, not sleeping at night (most of the time), thinking and keep walking. Always speaking something meaning less with no awareness of reality (live in his own world). Very stubborn and misbehaving with the family members. Keep on looking at the top and thinking with eyes blinking. Become irritated very easily. Won't bath for 10-15 days. Please advice.
