Thinking to die

Since then I started thinking of how people die just like that until I start thinking of what the dead are facing in the grave and will they now know the truth, but know it get worst I have start thinking maybe I should die now and know all what am being thinking about. So am afraid of what am thinking maybe is right or not please help me
