Listen to the people you respect, ignore the rest. And if you do want to interact with the community, for heaven's sake, don't respond to the assholes. They're just background noise.
Don't pay any attention to what they write about you. Just measure it in inches.
I would say, if anything, you should do your best to filter out the total assholes but not disregard all negative feedback. There's a difference between "I hate x software because I'm a FOSS fanatic and your company sucks and destroys the earth", which is pretty harsh and "fuck you, you're queer" which is just safe to ignore.
At least Bieber acknowledges that there's people who don't like him.
Worse, you simply accept that opinion as established, cold, hard fact, which means that in your own mind it won't ever change (the world will always be a shithole. I'll always be a loser, Anything I try to do to fix things is futile because everything's so horrible, etc).
"Great friends/family" just means more people to disappoint or fail in some way. "In the news" just means a bigger humiliation once you inevitably screw everything up and piss everyone off and let everyone down.
Essentially, anything good in your life receives a negative spin, and anything bad gets amplified in your warped opinion. And that only leads to more despair, lower opinion, more despair, etc until it feels like the only logical choice is to off yourself. After all, you'd be doing the world a favor if you ceased to exist. All those people you wouldn't be there to hurt or let down. All the outrage you won't cause. It's a net gain, really.
Does that sound fucked up? It is, but for the depressed, that IS their reality.
Unless you've been well-off, famous, respected, you can't understand just how big a gulf there can be between what people see when they look at you, and what you feel inside.
The bigger the gulf, the worse it feels.
You could even cut it to "you can't understand just how big a gulf there can be between what people see when they look at you, and what you feel inside."
I'm certainly fortunate and it makes my life a bit less stressful, but it doesn't keep me warm at night. It doesn't care about whether or not I had a good day at work. I can't have an intellectually stimulating conversation with it. And that's just a little bit of money. Fame would be even worse.
