Yeah I noticed it too, you can try and change your play-style - maybe calling feedalee to top lane to donate her few kills and some gold, asking her to camp botlane when she gets a little fed, asking botlane to put a good ward for tp, warding the enemy jngl (things that wil prevent your team from feeding, and pressure the map more)
I find it helpful just going midlane with a champ which good at roaming and gank non-stop, you don't really have other option, your team is bunch of feeders and you can't handle a fed adc, so helping the team in expense for your cs and exp is worth it for the long run.
