I'm wondering what the point of this reply is. It comes off as accusatory and obvious, given the comment you're replying to. Is having struggled with addiction a point of pride for you? I ask this as someone who's struggled with it. The person you're replying to went through a good deal of trouble to make it clear they weren't trying to be insensitive. It just seems kind of rude to someone who seemed to be genuinely trying to understand a horrible affliction.
I think the person I'm replying to used a lot of flowery language to say "Why can't you people just learn self control?" Invariably - because it's certainly not the first time I've heard it - there's an attached "(like me)" on the end of it. Next up: "I've never really understood why depressed people don't just try and make an effort to be happy"
