To be completely honest, I think I have lost faith in religion, so I'm skeptical about the afterlife. And no I don't need methods, I know exactly what to do, and last thing I want to do is encourage someone, I'm not evil.
Your signature does not reflect that you have lost faith in religion. It appeared to be a very sarcastic, harsh toned statement to me.
Any which way, before I was married, I had some major conflicts going on with my immediate family and I thought of suicide, just to teach them a lesson. I admit that now it seems selfish, at that time it looked like a sweet form of revenge.
First analyze why are you thinking of this option. Is it because of anger, depression, hopelessness ?
What are those reasons? are they long lasting reasons? If they are not going to last for more than few years, then why to look for a permanent solution for a temporary problem.
In short, I would suggest that instead of looking at the solution (suicide), re-analyze the problem and see if you can find a better solution for that.
