I think I have forgotten how to read

I have been trying to study for Step 2 and have been pretty much stuck at where I am at, or potentially even going downhill. Honestly, I have gotten to the point I just stare at questions, choose a random answer choice, then skim the question to see if that somewhat made sense. C is always the correct answer, right?

I need like a 250 on Step at least. I score a 20 on almost all the practice NBMEs. IDK what I can do to raise my scores or to even learn how to read again. All the words have lost meaning.
