KappaWing:
A lot of people on this forum, myself included, are concerned that you are planning to literally use the 'information' in this thread. Please address our concerns!
If you are seriously contemplating suicide, then I'd suggest stepping back and really looking hard at your situation. No matter which option you pick, all forms of suicide involve some degree of pain. Pain not just to yourself, and not just physical. I'm sure you've got family and friends - not to mention the people on this board - who would be devastated if you go down that route. When you prepare yourself mentally to end your own life, you end up dehumanizing yourself. You end up acknowledging your lack of self worth, which is inherently contradictory: You care enough to ask for a painless death, so you can go with dignity.
Don't worry. You're a pretty intelligent and respectable guy. You're not too far gone or crazy. The best thing for you to do, in my opinion, is find someone you can really talk to - and get some stuff off your chest. You don't even have to do it on this board, if that bothers you.
And if you are religious - please consider meditating on what your actions really mean, not just for you but everyone around you.
Good luck.
