Why must solo que be so unfair?

Ok. I know I'm just being a little dramatic, but I hate solo que. I mean, it's the only que I can do, being that I have so few friends who are on at the same time as me, but still. I recently got into a match where I asked my jungle for a gank, and I, playing Kled, lost skarll and couldn't fight. She gets caught, and dies. She then proceeds to hate spam me, refusing to gank any lane because she was a little sensitive, and made me so irritated, I left the game. I then realized I did nothing wrong in that situation, but she and the enemy laner still harassed me for no reason. I contemplated suicide, as I have before, and beat myself up physically and mentally for it. I honestly don't know why so many people are assholes on LoL. It's just a game, but people spend their entire time on it ruining the lives of others. I have been depressed for awhile, several years to be precise, and I may end up either commiting suicide beacuse someone made me feel so bad, or end up completely quitting in general. I really don't want to throw all my money down the drain, or that time I spent becoming half decent, because I have met some really good people through LoL, but at the same time I can't continue if people make me feel this way. So my question is this. Why must everyone be an asshole in LoL? I do nothing wrong on a game to game basis, and Riot still finds a way to make me want to kill myself every other game. I know its really just a personal issue, but I feel as if I'm not the only one with this problem.
