ha ha. i am surprised to see so many people have suicidal feelings for one reason or another in Sajha. I have one Japanese friend; she said she had a suicidal feeeling some 6-7 years ago; that time she felt like her life was useless and she was so unhappy. later she regularly went to church, made a lot of good friends and has easily overcome this problem. actually nobody is happy in this world, may be you should become  more spiritual or religious, or even a nun or Buddish monk if you really feel like you are unhappy. there was also a hot and hit model in Nepal, she bacame nun some 3 years ago to find out peace. or go for some week-long meditation trip or do it daily at home or go and visit your parents. keeping yourself very busy in your work or study also gives you better feeling and also you have no time to think useless junk like this.
