Worked so hard to get to silver last season

And now I got placed in flex bronze 5... how in the f+ck did that happen? Every game I lost I had 2 people or more feed hard in the first 10 minutes... I am getting tired of playing ranked. I dont know if the flex system allowed this to happen. I dont know if I got worse in the span of a week what I do know is that I am tired of feeding team mates and I am tired of the terrible attitudes that this game carries. I love this game, but god d+mn do I hate the people that play it.
