If you wonder whether or not to bring something up with a T, pdoc, support worker, etc., it's probably a good idea to do so. I don't know whether your worker is trained to assess mood disorders, but if they aren't then getting a referral to a pdoc would be a great option. It might help to chart your moods, there are a bunch of ways to do so online and off. I use an ipad app myself. That way you can provide a picture of your mood over time to the person assessing.
