heyo, i watched your match stream, and young sanity i understand your emotions are pretty high right now when you were playing that match.
you'll be a great guy in the future but you need to def trust your teammates more and not give up. you gave up on your team too early and let your emotions get the best of you. once you can learn to play for your team and understand that everyone makes mistakes i'm sure you'll be a great team player. for now tho, you need to keep your emotions and personality in check and that's what's holding you back.
i don't think what you wrote is why you got cut, i saw you giving up on your team way too early and it's probably the reason why. gl in ur future tho!
