How am i suppose to win?

Every game i get nothing but feeders and ragers. I cant even force objectives because they are losing their lanes by the 5min mark. I am just about ready to quit this game, any tips are HIGHLY APPRECIATED.

Things ive tried and failed.

*Warding for other lanes - Failed because they still over extend even after multiple caution pings

*Farm Heavy - Failed because they end up losing lane quickly(sub mins on average) and then coming to my lane immediately to take all the farm.

*Ganking heavy and often - Failed because they end up feeding their lead from jungle ganks

*Focusing on objectives - Failed because they lose their objectives too quickly raising the tempo of the game in the enemy's favor as well as giving them pressure to just came me because i am the only one worth anything.

*Banning for my team, Failed because they just end up feeding to the other thing that is picked anyways(example banning Irelia for top only for them to feed an Urgot)

*Getting fed and trying to carry, Fails because it just ends up as a 1v5.

These have been the most impossible games ive ever seen and ive been playing since season 4.
