I've been diagnosed with Type 2 Bipolar disorder, and that's the main reason why I'm seeing a therapist, but lately I've been heavily restricting my calories (trying to stay around 200cal/day), and I like it because it feels like I have control over something. I don't want that to go away, and I don't want to talk about it with him. Can I keep it to myself, or should I tell him anyway, even with the intention to continue doing it?
