If denial is what keeps you going chicken, let it be. If I asked for help and got responses like that I'd be quite upset. So no apology needed.
Well luckily most people haven't got a grudge against the world and feel the need to attack everyone who tells a friendly joke. The poster clearly unlike you took the comment how it was meant to be taken and far from being annoyed actually laughed! Which you still don't seem to have grasped. The poster wasn't in need of any "help", therefore an apology is needed!
i laughed, so my fate is sealed
