Diamond 5 stuck :/

Hello, So after having a very smooth climb to diamond 5 this season while maintaining a 60% win rate, i am finally feeling what my friends told me about how diamond 5 is just a ''trash elo full or ragers/trolls/feeders etc'' and i am not the type of person to complain about teams, i understand i need to carry to win and that some games are just simply uncarriable and all of that stuff but idk since i got to d5 i have met with people who just simply dont want to win at all.

Yesterday i had an adc who went teemo which tilted his support nami and that teemo just feeded the whole match right from the first blood and ended the game 0/10, now i get that might have been a bad game, but then i get a match that we are basically winning but our top and jungler decided that they should argue about ''who is more useful to get the rift herald buff'' and then our top just afk'd the rest of the match, and more and more of these games that i dont want to bore u guys with.

I am starting to think that d5 is just even worse than silver and bronze because in silver and bronze u can actually carry somehow but here its really tough to do so especially when u are with people that dont want to win, right now i went from 60% win rate to 57% and i am kind of stuck so i would like to hear u guys escaped this prison called d5.

Thanks and sorry for the rant kind of post.
