After a certain point, the number of games played does not matter much. I have multiple friends with 300-400 wins who are far better players than some with over 1000 wins.
Still, I'm not sure how you basically feeding helped resolve the situation at all. So you gave up trying to live or make any comeback of any sort? All I can say is enjoy your ELO hell. Everybody everywhere will tell you in ranked, you if you want to raise your ELO, you have to try every game no matter how bad it gets. No, you won't win them all, but every single one you do win is basically a 25 ELO swing.
