The central defender admitted his team should have continued their good run on Saturday but insisted Eddie Howe's men could not afford to dwell on what was a rare setback during their promising start to life in League One.
Garry believes Cherries have nothing to fear in the third tier and he called on his colleagues to return to winning ways by summoning the sort of resilience that served them so well last term.
The Dean Court outfit looked on course for a hard-fought away win when Rhoys Wiggins's superb free-kick put them ahead, but the hosts claimed an unlikely victory with quickfire goals from Kieran Lee and Oumare Tounkara late on.
Garry, one of the stand-out performers in the match, wants Cherries to learn from the loss.
He told the Echo: It was a great disappointment I thought we should have seen the game out.
Other than the shots they scored from, I don't actually remember them having a chance on target or any corners in the second half.
We're really upset with the result but we've got two massive games in the next week to 10 days and we've got to respond in the right manner.
I think we've got to learn from games like these when we are in what looks like control, then we concede a goal and then concede another goal out of nothing, and the game is gone and we've lost.
As long as we learn from the games like this and Notts County, we will become a better team and become better individuals through experience.
We know fully that if we see games out we can be higher in the league, which is what we want to do, so we're upset with that.
We can't dwell on it it's gone now and they won and we lost. We've got to make sure that when we play Carlisle next Saturday we put things right.
Losing is not a habit you want to get into but, if you do find yourself on the losing team, the next game you want to put things right. We did that for the majority of the time last season and we've got to make sure we do that again this season.
Garry added: There's nothing for us to fear in this league. We've got to be confident in our ability.
We've got to make sure, every day, we work hard, don't let our standards drop and see where that takes us.
I think we've certainly shown that when we're on full song we're a team you've got to be wary of. We want to make sure everyone sees that Bournemouth every Saturday.
