Support Hell is a Hell like no other.
You are thought of as a playable minion with absolute zero menace and contribution to the team. People blame you for everything and any kill you have has to have been stolen, even if you earned it. Even ASSISTS are considered taboo to a degree.
You are expected to be in absolutely every engagement no matter where it or you are on the map, even if you're already in one elsewhere. Your demands are so numerous and extreme even RECALLING is an absolute luxury. You are expected to carry out the roles of twelve champions, the the tank, crowd control, peeler, engager, and buffer all at once and have more items than the rest of the team combined with less than half of the gold of one, all the while being a hard counter to both your team that overspecialized AND the enemy team, all at the same time, while everyone insists that you have absolute zero menace as the support.
You are expected to rush sightstone first, even though no one actually pays attention to the wards you lay down, only to yell at you for not warding even when you have and then continue to not pay attention to them. You are expected to defend every lane, all at once, while you get yelled at for killing minions because you're defending lanes that no one else will. And the times that you are legitimately good is somehow unearned, that you somehow stole it from someone else or that you are hacking or cheating.
And then people wonder why no one plays the support. It is stressful like you could not imagine, and the demands are far greater than every other role combined; even being the JUNGLER feels like a vacation now.
Yet...
This is the only way you will get truly good: by taking the hardest role in the entire game and forcing yourself to be on par or better than everyone else. Outperform them and show them how weak they truly are.

. And give farm first 10-15 mins. All other is tasks for the whole team, not me.
. That's everyone responsibility. Toplaner, Midlaner, ADC and jungler must buy at least one fking ward.
or
. Then you watch your entire team pick nothing but squishes after and blame you for not picking a tank.
