LF Advice on Carrying from Bot Lane

Hello!

I am a support main, currently in Gold 3. I duo with one of my friends who plays ADC and we were able to easily climb through Silver to where we are now by duoing, but we have seem to hit a plateau where we can no longer climb higher.

My question is, what is the best way to carry from bot lane? I'm hoping that any support or ADC mains with a lot of experience could help me/us out a bit. Any feedback would be appreciated!
