Resistant depression: You're early (2 months) into course of treatment for what may be a resistant case of depression, possibly also with some psychotic features. Trouble with motivation, concentration, and energy is part of this, and may improve with more time -- or may require medication adjustments or changes. Your psychiatrist needs to know how you are, to help you resolve all your symptoms as much as possible.
