An old couple who are my friends, are so lonely that the walls are closing in/on them.
Is my phrase correct to say that they start to behave oddly?

You might want to use the phrase Stir Crazy. This generally refers to someone who's going a bit nutty due to prolonged loneliness or incarceration.
I do believe that the term "feeling the walls closing in" is anxiety. I has having an episode when I had a major presentation, a paper, a test, another paper, 4 classes (everything to this point was due the next day), an exam the next day, paper #3, and a dying grandmother. I'm in college BTW, but the feeling described above is apart of an anxiety attack.
