If there's any sort of beacon of hope on this dark day, it's really heart-warming to see support and talks of mental health from all over the world and even in Japan where he was nicknamed as Guile-kun by the Japanese Smash fandom. I also came across a fundraiser called "Flip the Switch" on Twitter and all the proceeds will go towards mental health awareness/research and suicide prevention.
Never assume you know what someone else's life is like from how big or small their presence/audience is and it shouldn't be the deciding factor of whether they have the right to experience sadness/anxiety/etc or not. Mental Illness doesn't discriminate and it can happen to anyone. Take care of yourself, love yourself, but most importantly, cut yourself some slack. It's so easy to be hard on ourselves because of all the standards we're setting based on what's expected of us, but don't do it at the cost of your well-being and sanity.
