im plat and dont know how to carry.

im plat 2 but I only can play top lane and play champions that are tanky ish and when I play trynde etc I get fed like I usually do ofc here and there I don't get fed but id say 6 out of every 10 games I get stupid fed and after I lose 40% of games even when im always fed how can I fix/carry harder looking for maybe a free coaching from a diamond 3 or higher if possible. but anyone that can give helpful advice that isn't stupid stuff like "split push put pressure tp ganks your on your way to challenger" in depth help with me and my choices and mechanics is what im looking for. thanks for your time
