I do this, too. Especially when we start some new approach or to tackle an issue. Like, when T first told me about dissociation, I read tons of stuff and every time it was like, "Thank GOD. I am not the only person who has this happen in just this way." Reading normalizes things and makes me feel so much alone. And sometimes it can help me see what's ahead (I like predictability and to know what's coming next). I agree that it helps to stop when you get distressed, because it can become consuming.
