Jamie Paterson had fired Forest into the lead just two minutes into the second half.
But Matt Mills directed in Andre Moritz's cross with 15 minutes left on the clock to make sure Bolton took a point.
Freedman said: "I'm delighted from the response of the players after the way that they were set back in the second half.
"But I wasn't happy because we created enough opportunities in the first half to take the lead.
"In the second half we made a very good Nottingham Forest side look ragged towards the end of the game. That's a great credit to our players for the way they showed that and with our possession and opportunities we created we should have taken the win.
"I thought the referee managed the game very well but I was disappointed for both sets of fans for how much time wasting that wasn't stamped down on."
Speaking about adding to his squad, Freedman added: "We're down to the bare bones at the back, so that's where we are looking to strengthen in January.
"But I'm not just going to throw money at it, we've got to do what's right by this football club."
