How do I carry games in silver elo?

I am on a massive losing streak yet my performance is not dropping. In fact, I end up being the most valuable player in most teams and try to carry but it feels impossible to carry games. I have tried everything from vel koz mid(11/3 with most objectives but still lost) and jax jng (25/7 but my team kept raoming and i couldnt 1v5 the enemy). Honestly, I need someone to help me as I dont understand hwo to esdcape the hellhole that is silver elo. I feel like my MMR is %%%%ed and every game I get people that feed to much, afk or troll becuase I cannot gank them in time.
