How if I dissapear ?

Sometimes I wish I could disappear from the world, one question. Have you ever want to die ? the world looks so dark and I always cry every night making my pillow full of tears. about disappear, then is it the best way if I disappear?  I am very afraid of fake people around me, sometimes I really hate myself if I look at them in the mirror, what should I do? My feelings don't get better quickly, I need the antidote, time is the medicine.  because as time goes by I feel much better and don't suffer anymore. but I'm afraid if someone comes to ruin my happiness again, because pain and bitter memories, will never disappear in someone's memory.
