When my depression really flared up, I started (and still do to some extent) relating my depression symptoms to that of HIV. You know, fatigue, loss
of appetite/weight, can't sleep, sleep too much, night sweats, etc. Hell, I even got really sick once (Winter last year), and my lymph nodes got really swollen. My mind always goes right back to it. Even when my family or a friend jokes about me being "skinny" or "pale", instantly my mind goes to it.
