An anecdote, that I at least find kind of funny in my own life:

I deal with diagnosed anxiety and OCD, and thus have read dozens of self-help books on working with these issues. A funny thing happened when I started reading the genre, in that I found myself somewhat addicted to it after the first 3-4 books.

I brought this up to my therapist after about the 10th book in two months, and he joked but also seriously said, ok, time to take a break, pick a few unrelated and fun fiction books and go to town on those instead.

Not offering medical advice here as everyone is different, but I've noticed a gradual decline in symptoms when I'm able to focus less on the issues themselves.
