Should I seek professional help because I have a lot of math books?
Personally, it seems to me that he was just making a joke. Awkwardly, perhaps, but still, just a joke. Your personal library seemed to him (and me) to be so &quot;over the top&quot; that it was hard to fathom. Had he said something like &quot;Wow, are you ever intense?&quot; it would have had about the same meaning.
It is possible that he had a negative feeling about it, but I really doubt it.
Or maybe a meaning like &quot;Wow, you need to learn to relax a bit.&quot;
But if you are so intense that you are ending up hurting your health, then professional help is actually advisable.
