Sorry you're depressed or at least feeling flat.

I've been listless and lethargic many of times, but one of the key elements of depression is anhedonia. So if you're finding yourself not feeling any pleasure about anything (sleeping, eating, others' company) then you are depressed. But you've already decided that that was/is the case.

Sending you big and hoping that an adjustment of your meds does you a world of good.
