I just got a 25 game chat Restrict

after a ranked game where i played bad and my whole team said my support was awfull, i didnt say much bit argued a bit i guess. Can you guys give me any suggestions how to improve, and how not to tilt during games where you are playing and have a bad team. Can you please tell me what i can do to be better, because i really dont wanna be that person. And i just checked my chatlogs, i can see im having a bad attitude, i realise why i get chatbans, but please help me out here? How can i stay calm during a game i get trolls and feeders and flamers, how can i improve myself?
