A Baruch College honors student shot himself to death yesterday after posting a disturbing Facebook message informing classmates that he was doomed, police sources said.

Raphael Blanco, 19, a Queens sophomore majoring in business and psychology, sent a friend a chilling message at around noon, the sources said.

The note read, “I am sorry I’m not going to be there when you go meet your wife, get married, have kids and grow old. Good luck with everything. I have the utmost faith that you will be successful. Goodbye bro.”

Blanco (pictured) also put up a Facebook status on his own page, telling his friends, “I tried. I failed. I’m sorry. Goodbye.”

Cops responding to Blanco’s Jamaica address found him dead of a gunshot wound to the head, sources said.
