Riot thanks for giving me smurfs trolls and a whole lot of things which causes me stress and anxiety

So riot I went around 18 kills and 6 death with mf and we lost a game due to our zed trolling and being toxic saying fuck you fuck you bitch fuck you. I can't control my temper but I took a deep breath. I dont understand match making system. I lose every game. The next 2 games I versed smurfs and they admitted it that they were playing on level 36 account. I did bad on those 2 games. I admitted I did bad against those smurfs. My winrate is 40% and I don't understand why match making system don't give me a better team and a easier team to play against. I feel like scratching my head sometimes and I feel like breaking something. I wish I could flame those who flame me but I don't wanna get permabanned. Why riot. If I try to climb u will make sure I don't. Im starting to grow more stress from this rank. My mmr was high but now so low that I gain 14 or 15 lp per match. Instead of being toxic I say we can win trust me. They flame saying no we can't u fucking bitch. Let's ff. I wish I could cry my heart out but will that solve anything. Riot if you hate me then... All I want is to pass s4 but its impossible because if I win a match I lose 10 after. Some are my fault I admitted that I'm not perfect and some I played bad. But mostly you know how it feels when you have a good day and u want to play some lol but you get someone in the chat saying I'm gonna troll because someone made me lose my promos. All I could say riot your match making system is messed up. Smurfs ruin the gameplay. Smurfs feel bored so they make another account to ruin other people's gameplay experience. I want to punch myself but I calm myself down. Everyweek to get 15 lp then lose it. I admitted some were my fault so don't be saying get better. Teams are like ur a bitch and continue to feed on purpose. Smurfs do this and they reply with I don't care it won't affect me. Smurfs are so.........
