Alan Archibald's side were once again left with nothing to show for their efforts on SPFL Premiership duty as Liam Craig netted the only goal of the game at Firhill on Monday to leave the Jags eighth in the standings after nine games.
Thistle have turned in a series of impressive performances so far this season but a lack of cutting edge has cost them dear on several occasions.
Doolan was the guilty party against Pat Fenlon's side as he spurned a glorious opportunity when clean through on goal with only keeper Ben Williams to beat in the second half.
But the striker is determined to bounce back and add to his two league strikes.
He said: "Personally, it was very frustrating, but for the team it was very frustrating.
"I will put it to be the back of my mind because there is no point in dwelling on it.
"Nobody feels sorry for us. I don't feel sorry for myself. I have scored plenty of goals, but you have got to miss as well. I will move on.
"From the minute I went through, I had my mind made up where I was going. I probably had too much time. The goalie stayed up and made me change my mind at the last minute.
"It is a lesson that we are learning. We have got to start taking those chances.
"I am big enough to admit that I have got to put that one away, I am honest enough that I won't hide. I won't hide from the next one. I will be there to take the next one."
Defeat on Monday leaves Thistle without a home win in five Premiership outings, with Dundee United, Hearts, Aberdeen, Kilmarnock and now Hibs all leaving Firhill with at least a point to their name.
But Doolan is confident the Jags can turn things around sooner rather than later as Archibald's side look to give the home crowd something to cheer.
He said: "Once it all clicks, hopefully it will fall into place. The fans deserve a home win and we are trying our best. We have got to look at that.
"We don't look back. We can only move on to the next game.
"The fans are absolutely incredible at this club. Ever since I came here, they have been the same. I really think they spur the boys on.
"We have got to trust each other on the ball to pass it about and they don't get on our backs.
"They are patient with us and long may that continue."
Meanwhile, SportTimes understands Thistle have ended their interest in striker Hannes Anier following a trial spell.
The Estonian, who is the brother of Motherwell star Henri Anier, spent several days with the Jags and appeared in a closed door game with the Steelmen, but will not be offered a deal.
