The current methods need to be moved to discussion. And you need to rewrite the methods because as she said this is discussion not methods, she identified methods as if there is someone going to replicate your work how he will be able to do that? Methods should contain the information about it.
Also she said the current methods are more like results and for the new methods you have to explain how you reached those results.
So what I want you to do is:
1- rewrite the methods based on the information above.
2- move the current methods to a discussion part.
