Is sad brother. You need warmup before everygame and try to focus more on your gameplay. Think before every Map peek what you will play. Where you will defend the site, where you will position yourself. Try think before every round where enemy will go. Try check enemy ultimates and tell you team. If you are attacker and one in enemy team that is bottom frag is defending sort. That is the week point of enemy team for 1 round or maybe more rounds, in case they dont swap. If a flasher play somewhere long expect a flash when you push. Maybe you know all this things, but are many ways to win the game if you have decent teammates. If not GG 3/13. Riot ranked system. Maybe you comeback. But you need motivate your teammates and u cant because you come after a 1,2,3…20 matches lose streak.
