His having different mood swings in different times.. Sometimes he is a very good person and some times his the most rude person.. He don't like to stay home he just want to leave free and also his getting addiction of alcohol in such is small age.. His always thinking that no one is better than me I am the best what I have it is best and no other person should have that.. Sometimes he also get jealous of his friends success...we think that maybe his having some medical issue that's why his behaving like this.. So we need the consultantion for him.
