What do I do in this situation?

My best friend Kim* really likes my other friend Colten* and they text each other a lot even thought they never met in person. Me and another friend Reggie* were trying to get them to meet in person. But things took a turn for the worse when Kim asked Colten over text a question and he didn't wanna answer. They got in a fight where Colten yelled at Kim, "F**k u!!!" and they both confessed to attempting suicide. Reggie and I have no idea what the heII to do and we're just so confused. HELP!!
