Can’t win a single game at the movement 2W/8L

I don’t know what to do anymore tbh, I have been training my aim plenty, always use util, stay positive to my teammates encouraging and uplifting teammates, giving callouts, and I can’t even reach my old elo (9-10k consistently) I recently got back to 8.5k then back to 5.8k right now, I understand you can’t win them all and there’s more to the game than fragging but they’re literally double my elo I even had them ask how I got to such a low elo & one said I’m the problem. What are some of y’all’s thoughts on this? How can I actually secure a win?
