Pray for a good support or play a mobile ADC like Lucian/Ezreal. Honestly, no one wants to actually help the ADC in Silver, so you have to either help yourself by playing someone who can peel for themselves or someone who has more ways to avoid damage. If you are a god tier ADC you may be able to get away without peel, but very few people in Silver are good at positioning or dodging from my experience.
I've moved for support for the most part and I've gotten so many friend requests from ADC's that were so happy to have someone actually trying to protect them for once. So that may be something to consider is if you find a support who plays a way you like, add them and ask to duo.
Otherwise, look on improving yourself. Pick the strong champions, abuse the strong items, go to champion.gg or probuilds.net to make sure you're building correctly. There are general improvements as well like practice CSing, learn wave management, place more wards, buy control wards, look at your mini map, use pings (not passive aggressively), etc.
