Why am i still alive ? what is my purpurse in life ? ( not gunna kill my self but please read)?

I am not you, nor do I know what it feels like to be you, but I had been told that I would be dead in a day, week, or month. I have an idea what if feels like to wonder, "Why the hell am I here"? My body is a piece of ****!. That was over 35 years ago. I still don't know why. I may never know. It's one of those things. It is because it is suppose to be. It is suppose to be because it is.
