In my opinion it's very difficult to get back once you've 'fallen behind' as a support, as this should mean that your ADC is also behind, in the laning phase ADC and Support have a sort of symbiotic relationship.

When behind (with your adc): Try to play passive, let your ADC freeze the lane just out of turret range. Ask your jungler for a few ganks and basically play to prevent any futher damage to your lane and team. If possible try to roam mid for to help with a gank or two, and try to encourage your team to secure Dragon's, the gold and extra xp is welcome.

Accidently feeding? That's a matter of proper warding, map awareness, positional knowledge and champion knowledge. I suggest watching LCS games to learn a lot about that, did wonders for me.
