My son is 33 years old, married for three years, achiever, working in a MNC, everything is hunky dory but in d last one year he is very obsessed with abs, pumping up and body building and has been taking zomacton (somatotropin) hormones for the last one year. He is very withdrawn, has mood swings. My daughter in law says he is absolutely disinterested in physical activity. Has no vices whatsoever. Well behaved, is not very social and is an introvert .He is feeling life is meaningless and has suicidal feelings at times (he has contemplated suicide when he was alone) he is not gregarious by nature. His routine is office, gym,eat n sleep and on weekends sleep a lot. His life has all d pluses, loving wife, v Good education, loving sibling and parents. V good job U name it n he has it all but of late he asks about d purpose of life and wants to write a book on it. Doesn't party, v occasional drinker, no subs abuse ever, no smoking or womanizing. While talking to his wife also, at times goes into a shell and wants to b left alone. What could b wrong? His wife is v chirpy and not at all demanding.
