Reforming advice?

So recently I've been chat restricted and I deserved it. I'm not here to give excuses. I acknowledge what I did to deserve that restriction. I'm sure everyone in the community gets mad sometimes. League can definitely bring out the worst in us, even when you don't want it to. So in result I am unable to get rewards from Hextech, which is understandable. I had read on the boards that in order to lift the restriction, I have to reform until League of Legends feels that I have.

Honestly, I really want to reform but It can be quite tough. I assume that whenever you get punished, you automatically get moved in to a queue filled with other toxic players in the same situation as you. I think this queue needs to be reworked a bit, for I don't think putting a bunch of "toxic" players in one game will allow any of them to benefit. In a game of toxic players, all you need is one person to get heated up, in order for the rest of the players to start flaming. From experience, it can be very frustrating to play with toxic players game after game after game. It's hard for me to consider playing games nowadays because I really don't to get into a game filled with more toxic players that will ruin my day even more as well as being forced to cooperate with them.

The reason I'm ranting right now is because I feel like I had just played one of the worst games in my league career. Today I had a game where I had fed FB once, and a couple of premade players, began to harass me all game. They would not stop, constantly harassing me. They kept saying Americans suck (they meant to say North America as a whole), so I'm pretty sure they were playing from overseas (which is besides the point). The support duo started taking my cs and harassing me, so I decided to go into jg. From there on the duo just harrased me in /all chat and kept telling everyone to report me. From there the enemy team just started ganging on me. One of them told me to get cancer. I was trying really hard not to flame back, as frustrated as I was at that point. So i decided to mute everyone in the game for the first time. At the end, I just got harassed and reported.

I wouldn't say that I have anger issues, but there are times where my pride really does get in the way. Over the years I have definitely toned down the toxicity in me significantly, but I admit, there are times where I still get heated from games (which I shouldn't be). Honestly, when you play your hardest every game and you still get dragged down and harassed all the time, it can really lower a person's morale. I could /mute all every single game, but as a player I shouldn't have to be resorting to that in order to feel safer in a game.

Can I get advice on what to do in order to persevere through reformation?
