Hello FLG,
I feel the same way sometimes too. I try my best to avoid it, and I also try to think that maybe the person was just super busy but wanted to say something to be supportive. I'm not sure if that is me being naïve or not. Anyway, I wanted to let you know you're not alone in that thought.
At the same time, most people on here have been really awesome and I've made some very supportive friends. So there is that.
