Suicide under necessary conditions?!

There is no fast painless way. You just need balls.

Currently you can do an operation in which doctors will install for you a button inside the ear (for safety purposes which job is to cut the electricity from your brain, am not sure about its mechanism but i know that it doesn't directly cut the flow but it has a timer and it gives you time to change ur decision but once you continuously press it for 5 seconds there will be no return.

Go to a place first where no one knows you. A very nice place where you feel very peaceful. After that you will feel very good and will do what is best. Because atleast try to live life for one day before suicide. If you are enough depressed then blindly follow me without thinking i.e. goto a very nice place (anyway money doesn't matter for you this time) then proceed your thought. Have a lot of Beer, Vodka with some cigarretes for two days. Condition is second day you don't have to eat anything. This is the best painless way. But first go to a good place and do this there.

There is no painless way lol even with a lot of things around. It would be very slow and painful in such a situation :) and you might even survive it lol just come out with disabilities so its a bit of a fail...

Suicide is not a solution.

hold your breath
