I could understand and feel for Barry's desperation in this situation.
He seemed open to each and every option everyone else came up with, and he was the one who put the kibbosh on using time travel, it's just nobody else's plan worked up until Iris came up with the idea to use the energy of the Speed Force.
The only time he lashed out at anyone was when Jay told him he couldn't throw the nuke into the Speed Force but he apologized for it afterwards.
If anything I'm just a little bummed that Barry couldn't figure out a way to save everyone and needed Iris to give it to him.
