I never knew the man or experienced anything he created, but hearing about anyone's passing -- suicide especially -- hurts. No cry for help should ever be taken for granted.
To everyone:
If you're in a good place, please do everything in your power to contribute towards the small but significant amount of goodness that exists on the internet. Every little day-to-day interaction contributes towards our state of mind, and you never know when something you say will make a difference to someone else.
If you're in a bad place, please do everything in your power to avoid all of the negativity that dominates the internet -- even if that means going offline entirely. Find the people who make you feel like you matter, who spend time with you, who make you smile. There's no quick fix for anything you're going through, but if you can go to sleep later thinking today was pretty good, tomorrow can be too.
