Boro were searching for a seventh straight victory, but could count themselves fortunate to escape with a point as Reds striker Billy Sharp was denied by the woodwork late in the second half.
But Proctor, deputising for boss Tony Mowbray, who is still suffering the effects of a virus, was pleased with a point.
"We're delighted. We would have liked to have won the game, but this was our third straight away game and we looked a bit jaded. We were playing against a very good Forest team who have some good players. We always knew it would be a tough game for us.
"All in all there were opportunities at either end and a draw was probably the right result. We had a couple of nice opportunities on the counter-attack, but I think the biggest thing that came out of us was the spirit of the boys.
"On the back of six big wins, it does create a good spirit and we needed that here. They put us to the sword at times and made it very difficult for us. This division is very difficult and is demanding, emotionally, mentally and physically, and we did well to come out of this with a point."
