So, an online acquaintance of mine has mentioned that they're suffering from severe depression recently, and my natural response is to want to offer them support and encouragement - maybe suggest that they should see a psychologist and get some medication for the condition. However, I'm uncertain of how to do so, since I remember reading that depression can cause you to interpret things that people say to you in a negative light, and it's my understanding that the American health system is not the greatest, and thus they might not be able to afford medication.
How should I approach this? Naturally, I don't want to do more harm than good, and cause them to start thinking things like "he's being smug about how his country's medical system is better than mine" or "I can't afford medication; I'm worthless because I'm poor". Are there any general guidelines on how non-medically trained people should approach interactions with depressed people?
