How about trying out sports? Swimming, Basketball, Futsal can be good activities that can make use of ur time and maybe make u spend less time thinking about ur suicidal thought.

And also sports makes u more healthy too, it'll drive u mentally to the right path.

Then how about sumthin dat requires more brain power. Like picking up Sudoku, Minesweeper. Nowadays android and ios many of these addictive games that needs u to focus and use a lot of ur brain power. Then maybe it'll draw u away from the suicidal thoughts.

judging by ur info, it seems ur life is good. Why the suicidal thought?

Maybe u can search youtube for Nick Vujicic's video for some inspiration on life.

Is it bcoz u are too boring and having too many leisure time not occupied? It's like, you duno what to do during those free time, so ur mind wanders....

Try chatting with ur best friend or colleague or friends. That's what friends are for. Whenever you have the suicidal thought, call ur friend, ask them to go out yamcha. Chit chat with them. And maybe u can open up to them. Tell them about ur suicidal thoughts. Sometimes when u open up and tell what is bugging you, you will actually feel more relax and the burden is like not so heavy dy.

Good luck bro. Life is too short to not enjoy it. Just enjoy life as it is.
