As a support?

Stop feeding.

It's true that your KDA can be effected when the laning fase doesn't end well. But you really have to stop thinking the game is over on that point. Their are a lot of things you can do where you can impact the game with. Things like that are very situational and it really takes experience to known what you have todo in order to get back into game. Sometimes I vision controle in order to prevent ganks, others it's just zoning and let your team outscale them. While others require roaming to shift more power towards one of your other teammates. Sometimes your plan doesn't it and you will only have a split second time to change your strategy. Overal the support role is just like the jungler a mindgame. Sometimes you fail while other times you turn it arround and win a 4v5. You have to understand your win conditions but you still need a dynamic mindset. Reading guides can help but it can become a trap add the same time. If you lose a game and don't understand why, in 90% of the scenario's it's because you strategy wasn't impactfull enouge.

As a support, its hard to guess whether your adc is agro or passive tower hugger,
gets easier with time, sometimes it is frustrating when the 1000hp adc lets go of a 10 hp enemy to live another 5 mins XD

I get you well, but if your adc is a tower hugger and have no presense, try not to go 2 v 1 even if it means harassing them, as long as you can delay the tower destruction you're good. Only go agro if it ensures your safety. Protect your team and do the best you can to win. Thats how it should work :P

Are you a smurf?

When my adc mentions it I stand behind them and when they cant farm at all they will notice. Yes they have to farm but the enemy isn't just gonna allow that so either help me and suppress the enemy or don't help me and get suppressed your self
