I think its time for me to end my life, need to stop being afraid of death?

This is not a sob story to look for attention, its the truth. I was born with minor APD but its barely there anymore. I am very shy, touchy, and sad all the time naturally. It's my personality. All I've done was try to make people happy all the time, so I almost always chose to to what's "nice" instead of "right" to spare peoples feelings which basically left me being the loser jerk with no friends. Everybody here hates me and wishes I was dead and its my fault. I'm better off dead. The fact that I'm so scared of it just make me even more of a jerk than I already am. Me dying would be so much better for my family and former friends. And this is not your usual depressed teenage girl (im 16). I'm a very bad person and need to know how to atop being afraid ans just do it. What do I do?,
