Fernando Alonso was left bitterly disappointed by his retirement from the Canadian Grand Prix on Sunday.
The Spaniard was touched by Jenson Button on lap 37 after seeming to turn in on Button going into Turn 3.
The collision spun Alonso into the wall on the exit of the corner, forcing the fourth of five safety-car periods of the afternoon.
"Everything went wrong, right from this morning when we saw it was raining," lamented Alonso.
"It's a real shame because today we really had a good race pace but we were unlucky: that's not a feeling I have, it's a fact."
Alonso felt that the decision to start the race behind the safety car was wrong, and deprived him of a key opportunity to attack polesitter Sebastien Vettel.
"We had our best qualifying of the year and we found ourselves starting behind the safety car, when I felt that for me, the intermediates were the best tyre," said Alonso. "When we fitted them, the downpour came, along with the red flag which meant those who had not changed tyres could now do it practically for nothing."
Following the downpour and the two-hour red-flag period which followed, Alonso pitted for more intermediate tyres after the safety-car restart - but was out of the race before he could complete a lap on them.
"Finally there was the coming together with Button, which as a final insult left my car beached on a kerb and I was unable to get going again," he said.
The non-finish leaves Alonso a staggering 92 points behind championship leader Vettel after just seven races, and the Ferrari driver admitted that the title race is now already beyond his control.
He is, however, staying positive about Ferrari's improvements during the weekend.
"The championship is not finished yet, but we must now hope for errors from others to have some hope," Alonso said. "Our performance level here was good, especially because of the characteristics of the circuit, but also thanks to the updates we brought here."
"We must keep our heads up, have confidence in our ability and work hard."
