Vent all you want. Some games are just won or lost, its a game with 5 people on each team in summoners rift.... you will find no pity. Learn from the game, stay in good spirits, and things will get better.
As a support main believe me when i say your top lane issues do not hold a candle to the problems that happen if my adc is reckless or if we are ganked non stop because of dragon (which we have to keep an eye on to keep the enemy from getting it).... and yes, if the adc fails, the support tends to fail, if the support fails, the adc tends to fail.... and sometimes the play styles just do not mix. Thus leading to a horrid bot lane game.
Not saying top lane is easy, but your "poor me, my bot lane lost me the game" is not taken too kindly when if you didnt want to play with randoms, you should join a team and get out of solo queueing.
Enjoy your loss, hope you win sometime too :)
