Remove chat feature

I believe league needs a remove chat feature or remove the ability to chat for those with mental health issues. Because of my mental health I literally have urges i cant control to type negative things that I wouldnt normally type or say. This has led me to be depressed and frustrated as I felt league was bullying me by taking my own words and then building a case to have my account banned- which it eventually was. I felt like league has labeled me or others with mental health issues as "negative people". If this game has a right to ban people over speaking "negatively" in chat, then the game should also offer an alternative to not let someone escalate themselves to the point of being banned. I feel like this targets a small group of people, myself included, to end up banned and if I had a feature in the game to not type in chat I would never be escalated to the point of permban. Someone linked me a thread to do this in a way outside the game but I felt like it was too difficult to do. There should be a feature in game like a box that you either check on or off. Maybe instead of giving someone a final warning to be banned they get a final warning that their chat will be removed for life. I believe this is a better alternative to include everyone and enjoy league of legends by the standard it should be played. As of right now I feel like league of legends discriminates against those that have extreme levels of mental health issues by just removing them from the game entirely.
