my online friend who has problems with his parents and also his mental condition is no longer active now

soo- i had a friend, we met in an artist group, and he's a very great artist. he last chat me yesterday, at 12 am- he asking for help, and unfortunately- i didn't active that time. and then, at 1 pm- I replied, "Why??". and he didn't responding. i already spamming him, and i also checking his other account, and i asking his irl friend- but his irl friend tell me that he haven't met him since the morning. sjzbuejshdus- he's a suicidal person and i hope he doesn't doing that things... i wish i was active that time
