How do I really become a lich?

Please don't take me as and idiot that plays too many games. I'm just so sick of people, they sicken me, they're just so damn unreal, I can't believe all the things wrong with them, it makes me sick to my stomach. I really do believe there are only things out there though. Supernatural or not, I believe in some sort of magic and I'll do anything to not be human... But I don't want to die. I want to become a lich. But anything will do as long as I can keep my mind and still move. I won't betray my religion of following lord Jashinsangel though. Please understand and please, someone out there help me.
