This isn't realistic.

I've dealt with depression before.

People will say they want to support you and want to know what's going on. If you describe a problem, the person listening almost always offers a solution. If you start to explain why their solution won't work, they almost instantly get super annoyed and may suddenly become unavailable the next time you call.

People want to think of themselves as the type of person who would be supportive of a depressed person, but most "supportive" people who feel this way still adhere to normal social mores and expectations and get pissed or annoyed when a depressed person doesn't follow them. It's also super hard for a depressed person to simultaneously discus their depression and adhere to unwritten social niceties.

If I as a depressed person keep my feelings to myself, if I get better I still may have friends and if I die at least some people may show up to my funeral. If I lean on non-depressed people for support, they will expect normal social responses that adhere to unwritten codes and will get annoyed, the result being for me at best fewer friends and at worst a cremation with no one who cares about the ashes.

Honestly fuck that tweet or whatever. Shit like that is bout making society feel better with corporatesque platitudes like "Mental Health Awareness is Important! See something say something!" or whatever empty cheerleading slogan exists to encourage the workers while the most poor of all rot on the street (unless they fall asleep, causing them to be arrested, whenceupon they are fed in jail). Most people do not give a fuck, that's why a homeless subpopulation exists, fuck this planet and fuck empty tweets like this.
