He needs help. He's been posting a lot of stuff like this over the last year or so both on Facebook and Twitter. These are obvious cries for help, much like Sinead O'Connor. Somebody close with him needs to reach out to him and seek help. I would be devastated if anything happened to him. He is so talented and a genuinely beautiful person.
I'd like to think he's saying don't say R.I.P. for when he dies, because he won't be able to see it anyways (which I don't agree with mind you) but knowing him it's probably something else. He's been battling depression for years and I'm really scared it's starting to catch up to him
