Cover art for Go Insane lyrics by Lindsey Buckingham

From everything I have seen and heard related to Lindsey Buckingham's life, this song was a response to the craziness that his then wife, Carol, was causing. She was unbalanced. It was basically a song talking about how she was driving him nuts, and all the rumours that were going around about his marriage troubles.

Now, this part is only speculation on my part, but "She's a lot like you" likely is hearkening back for his former flame, Stevie Nicks.
