Position rank too hard for bot player

I don't want to say this but I don't care you guys say that I don't know how to play the game so I lose a lot Basically, before we have position rank, we can play jg/mid as a way to carry your team and get rid of iron/bronze elo if you know how the game works (like the principle of helping, ward/vision, the basic understanding that fight or not to fight). But once we have the position rank we have to play one position from bronze to gold or plat. I know it is easy for mid and jg players with the matched ability but on the other hand, it is too hard for ad/support player to carry the team as a single player.

I was not planning to post this discussion until I met a mid Yasuo did 1800 dmg in 20 mins game while I play thresh sup with 2900 with my ad who even can't dodge single Q from Caitlyn.

As an old player began this game since Season 2, I clearly understand that things happened to all the players and it's often that you face a bad situation like you play mid and their mid & jg duo to focus on you. But at least, I know that the game doesn't end just because you got killed once or twice, or one to two mistakes your jg made, and you still have methods to face the pressure and try to make a contribution to the team. But an 1800 dmg Yasuo really broke my heart as a sup/ad. You literally just do all dmg/use all your abilities to protect your ad before you die and watch the game lose.

currently, I can do nothing with climbing, maybe I'm not lucky enough to have a mid/top/jg teammate to at least beat his or her opposite laner at least once. My situation rn is just winning a game, get 44 lp, lose 4 with losing 9 each time, and so as a circle.

I know you guys could say that I'm in the elo because I deserve it. I really don't care cause everyone says so when the game about to lose. maybe it is time to stop to play this game. I mean it's already 6 years, and I don't have to stay on the game that I should have a better result but can't.

Thank you for reading, again I don't mean sth to that yasuo or all the teammates I met cause everyone got right to play a game the way they want. I just feel sad about myself and kinda regret that I didn't get higher elo last season so to make this season better (used to be a flex player)

It is just...to hard for bot player
