You think of how much fun and free and how much OPPORTUNITY for growth and personal development you'd have by LIVING and MAKING THE MOST OUT OF IT.
There will always be troubles, problems, tests, unwanted attention, feeling of inadequacy and what not. But it's not the end of the world. There's always tomorrow to look forward to and to try and have as much fun and learn as much as WE WANT TO.
Pray to God, and get help from a psychiatrist! And think seriously about what would happen if you did commit suicide. Your family would be devastated and absolutely heartbroken! Think of all the people who love you and care for you.
