Personally, I think what you do is something wonderful. I can tell from your posts here that you are a sensitive person and genuinely care about others. We need more people like you here. I'm not sure why you need to draw boundaries with people whom you care about (like people in your personal life)?! You might not be able to change their situation instantaneously, but I'm sure you can make them feel at least a little better, and I think you are one of those people who helps in doing so by showing empathy to others, instead of bombarding them with emotionless and critical advice like some people here who I doubt that they help at all. I think I'm not as helpful with others, but I try to help when I feel someone is in pain. But if I failed in person (which I usually do because of my lack of social skills to express myself), I would imagine how they feel when I'm alone. I know it's not helpful for them this way, but I guess it's the way how I empathize with others whom I care about.
