Due to it's mental demand, instrument flying causes everyone to have difficulty with it at some point in the training process. That being said, if you at the approach stage check point, and are having difficulties with maintaining heading/altitude during bumps, you may need to take a step back and do some basic attitude flying.
It sounds as though your scan is deteriorating as the workload increases. When this happens, your nerves cause your brain to hiccup resulting in overcontrolling the airplane (like a kneejerk reaction).
I would suggest practicing on a FTD. I know it is not like a real plane, but it will help you practice your scan and to keep your inputs light. This will also allow you and your instructor to determine if you may need to take a few days off to let your brain rest. If you are pushing yourself to finish the stage check, you may be sub-consciously adding stress to an already critical flight scenario.
Good instrument pilots are becoming rarer. In this profession, it makes for a long day when you have to work with someone who doesn't know how to fly IFR. Don't worry about finishing, worry about being a good pilot.
Best of luck - let us know how it turns out.
