My sub committed suicide…

Hi I’ve been a dom for about a year now, not much success until recently and now I’ve just learned one of my subs committed suicide. I have his phone number so I texted him on a few occasions after it happened, then I received an angry message from his mom blaming me for everything. Has anyone ever dealt with this? I feel extremely guilty and I’m not sure what I’m looking for exactly, just want to know what I’m not alone.
