I think he was, but the way he said it, it sort of felt like he was dismissing my depression. I knew he meant well, though.

I came into that therapy session bawling my eyes out because I was severely depressed and suicidal. He kept asking me what caused my depression, and I responded with, "nothing". He kept insisting my depression was due to something, and that's when he proceeded to give his "example"... but bipolar depression often happens without a trigger. There is no environmental trigger.
