Suicide?

So my friend has been having a lot of family issues lately and he’s been acting bizarre. He texts me multiple times a day and he didn’t text me back for three. Last night he texted me saying that he needs to call me and I haven’t heard a word from him today. He was saying it was about me but I have no idea. He deleted everything off of his social media, which is super odd. What do I do? I’ve texted him three times and still no word. What would you do, I’m getting really freaked out.
