Why is this game so bot lane focused!?

I don't understand why who ever wins bot lane wins the game? It makes me feel like my lane doesn't even matter and feels shitty when i win lane but there bot lane comes and 3 mans my lane while my bot lane has to farm since there so behind. It really makes me not wanna play at all since i feel like a meat shield for my adc.
