Here, I don't know where you think I came from, but I assure you its from a place that has known its share of depressed people who were on the edge; most feel powerless, that their lives couldn't possibly get better, that the end is near, and I found the best way to deal with people like that is to have a FUCK IT attitude; go on, go live life the best way you like .. No point in crying over them, telling to go see a shrink, or take meds, sometimes people don't want that, they what hear someone telling them to grab life by the balls 'You can do this'. And then they might go in to therapy and/or take meds.
I use to run brothels where some of the most fucked up,low self-esteem, mentally and emotionally batered people you ever want to meet were found, but I inspired them, made them feel confident, and installed the motto ''I can do this', now, the brothel wasn't the only place I use this brutally hardcore mindset, I harnassed it in the foster homes and group homes of San Francisco when I wasn't at home with the family, so whatever works for you, fine, but I also know away thats equally affective.
