"It's really difficult to have to live with everything which is happening this season," Gisdol told reporters.
"We've practically not had a single normal game yet. It's crazy to see how the ball keeps going into our goal.
"Looking at the first half, it's totally unfair that it finished 2-2. We're having to stomach a lot and it's really starting to get on our nerves."
Hoffenheim have the third best attacking record in the division.
