there are a billion things that could be going on, from you falling behind in farm late game to not being at fights to whiffing skillshots consistently to trading 1 for 1 when you're fed to being unable to tell wtf is going on in a 5v5... etc.
But as a general concept, when you have a lead you have to think about how you're using it to impact your teammates, secure objectives and get closer to actually destroying the nexus. like, you can shitstomp mid as zed but if all you with the lead is go deep in the enemy jungle with no vision no map pressure and trade 1 for 1 with the enemy Janna, or you keep teamfighting when the enemy team has great peel for their carries to keep you away, your lead might as well not exist.
and yes, climbing silver is frustrating because even if you have your basics down there are tons of things you don't think about that you should have internalized, you can't process new information fast enough yet or you just don't have crisp mechanics yet. I remember when I'd feel like I had done everything I could as a Silver 3 to carry games but I was winning only half of them; that's your blissful ignorance kicking in.
