Steve Sidwell put the Cottagers ahead with a first-half strike before Gareth McAuley's late header ensured that the spoils would be shared, leaving Fulham with four points from their opening four games.
Jol's men had three goals ruled out for offside prior to the equaliser, but the Dutchman thinks that Fulham should have made the most of the opportunities they created.
"We have to take it as it is. We have to take it on the chest, pick ourselves up and go on," he told Sky Sports.
"It's not easy to find these high expectation levels on the other hand, we should have won this game. We should have scored the second goal, we had three or four opportunities - Berbatov had two great chances.
"The keeper did well on the first one, the second was a volley and I don't think he was offside when he scored.
"Of course there was one he should have scored from close range and he didn't so I think it was in the net three times and it didn't count.
"So we were a bit unfortunate but on the other hand, we soaked up the pressure. There's always a chance to concede a goal and that's exactly what we did."
Jol also bemoaned the manner of the equalising goal, with Gareth McAuley converting a Chris Brunt corner in the last minute.
"The corner kick - we should have done better - if you attack the ball, you don't give them the chance. It was a good leap but on the other hand, we've got good defenders, we've got all the size in the world so to concede a goal like that is very disappointing," he said.
"When you saw the last 10 or 15 minutes, we looked a bit tired. Of course we had a lot of players on international duty, but on the other hand, the main thing is to keep going and score a goal and then it's over with.
"We couldn't do that so we have to live with that result.
"I feel we played almost the same as we did against Sunderland in the first game away from home. I think the balance was better because of course, we had the new players, but even Bent was out with an injury."
