My golden rule for freediving is simple:
- The most important and critical part of pre-dive preparation is to be absolutely motionless for at least 2 minutes prior to the dive, and at least 5 minutes if the dive is near one's max depth

Having to fight a current at the surface is a total violation of this rule, and I would say that the working depth is cut in half at least. For example if you can dive 70ft under ideal conditions, and you are fighting a current at the surface, I would say your working depth would be 20-35ft.

You say you don't remember feeling panicked or out of air. That is not necessarily the case. Your blackout was long, and the longer the BO, the greater the memory loss. It appears your memory ends just after you shot the fish. This means that any panicked ascent or big contractions have been forgotten. It doesn't mean that those things didn't happen.
