Feeling hopeless

Just lost my last like 5 comp games after having a really good set of placement matches for competitive, and my last team mate on co vangaurd let me have it pretty hard. Not entirely unfair i was getting killed alot as Rogue, but i feel like i'm not gonna get much better than i currently am, im not like the most prolific player or anything of the game (my account says i have about 33 hours of the game so partially my fault for not realling having alot of play time but my win rate is below 50% (249 matches played, 124 won, only 6 comp matches won of 19 jesus.) and i dont tend to get mvp or svp and usually I am the weakest player in the team

Im not really sure what else to say here, i do my best and try to play my heart out and get better, i cover roles that need covering which means i dont get to really play duelists and i just kinda feel bad about my ability to actually contribute and play i guess. Thats all i really wanted to get out. If anyone has any advice or anything to add i wouldnt mind hearing it, even if its just kinda brutal. Thanks for reading
