I just stumbled on this on Reddit, which turns out to be one of the best places to learn more about issues from people who you can relate to.
Last week, I was feeling not so great and a couple of my friends made things worse by asking me why I'm depressed. I was upset with them. In my conversation with the BF, I vented my frustration. He said something similar to what the article in the above link refers to: people who act like how my friends did are not indifferent but are ignorant.
