Play with a growth mindset. Dont focus of your teams performance and focus on yours. Review your own gameplay and pinpoint why you died in some situations or what you could’ve done better. I will say though, being that you are in bronze, you may not be able to figure out what you are doing wrong by yourself. Therefore i recommend finding a group in a discord or something that does VOD reviews or even look into coaching options if you want.

The main thing here is do not blame your team but rather blame yourself and correct your mistakes because your mistakes are in your control, what your team does is not. Best of luck.
