Please Help Me.

So, last night I was being unsportsmanlike. Well actually, more than unsportsmanlike, worse. I am deeply sorry for what Ive done and from the information Ive found you cannot appeal for behavioral / toxic punishments. I just wanted to apologize for disturbing the peace in the community. Ive been playing league since about 2013 or 2014 and I'm gonna miss playing. I'm not gonna bring up how much money Ive spent on the game because there really isn't any point. I just wanted to apologize for what Ive done and apologize for being so immature. I do not think I'm different from anyone else asking for an unban but please give me one more chance. I don't want to go through getting up to level 30 again and I really worked hard on getting that level. I've won 7 of my placement matches and I had 3 more games until I found out what rank I got. I was doing great and I don't know why I had such a disturbing break down. I would have submitted a ticket but I couldn't find a specific reason on why to submit the ticket. So I'm just gonna put it here under "Player behavior & moderation." I want some opinions from the community. I know that I've gotten many chat suspensions and one account suspension in the past but I regret getting those and I deeply regret disturbing this community's peace, so I am hesitant of posting this and I expect rude/truthful replies like "If you were given this many warnings, you wouldn't have done this, do not waste time in writing paragraphs and apologies." and "You deserve this if you've been punished so many times." I know, and I realized that I did wrong, and I am deeply sorry for what I did.

Thanks for reading.
