sometimes life is so hard to handle.

sometimes life is so hard to handle. i just wanna die.once my friend told me about a pray for this. i dont remember the arabic but i remember the meaning "tuhan jika hidupku berguna maka hidupkanlah aku, jika matiku berguna maka matikanlah aku". everyday i whisper this sentence to the lord since junior high. i do not think my life is useful for anyone or anything. but the lord has different option. i just wonder what is my role in this life anyway
