Why is League so damn stressful now?!?!?

Every single game i get either A:Bored B:Stressed or C:Pissed off 90% of my games feel like they are over in 15 minutes and its better to just surrender. You either stomp the enemy team, or they stomp you, the game revolves around the most OP picks in the current patch and you cant have fun playing other champs because you just lose. Previous seasons (Before S6) you could always say "dont worry, i can carry this" to yourself and you did have the ability to do that. Currently and over the past year, if you lose 1st tower and your team has 3 deaths, there is almost no possible chance of you winning that game from a comeback. When you stomp and have no fun, youre Bored When you KNOW you can win a game, you get stressed out by teammates and they want to FF When you KNOW you're gonna lose the game during champ select(argument/bad matchups) or 1st 10 minutes of the game(lost 1st tower/botlane feeding), you get Pissed off. Its to the point ARAM is starting to feel more fun. Riot Please, give us something, give us an actual response, not just some update that nerfs the current things and somehow you manage to mess it up and make a new champ OP
