<human>: My friend messaged me the other day with a big long text talking about how depressed he's been these past couple of months, mentioning how he doesn't want me or my 2 other friends to bring it up to anyone. We've been best friends for about 3 years now.

He stated that he doesn't want to hang out with us anymore because he will only bring us down due to the state he is in and does not want us messaging him, I'm not sure if I was right to, but I sent him a few messages trying to give him some support and tried to call him twice, with no answer nor replies.

It's been 2 days now since that message and I haven't heard from him, it shows he's online on facebook sometimes so I'm not really sure how worried I should be.. My other friends don't really seem to be mentioning it either.

Sorry if this is the wrong subreddit to post to.

Can you provide a brief overview of the text?
