Jumping under a train is bad for the public, the driver, the families of the departed and just about anyone who sees or hears about.
Guys to be honest hes probably already done it, theres been an influx of suicides on the railway in the last 4 months in Harlow i know at least. 8 people in 4 months with the latest one last thursday, thats one every 2 weeks. It's like its the latest craze or something.
If your not happy with your life just think for a moment and think what makes you unhappy, desire causes suffering basically, take a look at some Buddhism websites or books they can help you through alot.
Just take life as it is and remember that everyone goes through trauma you just have to face it no matter how hard it is. Suicide may seem the easy way out but in truth its the cowards way. Life has its ups and downs and you gota take the highs with the lows, the good with the bad and just live.
Theres no turning back once you're candles' gone out. If it seems bad now just remember theres always the good stuff to come along still and you can't experience it if your not here anymore. Just help yourself on this one and keep your head up!
