This happens to me too- I think it is both that I feel like I am utterly unworthy of the attention and good thoughts (any time a person did me a favor growing up, my mom would say "I hope you know they didn't have to do that for you and they really shouldn't have, and I hope you're grateful for it, you need to write them a note thanking them from the bottom of your heart so they don't think you're a spoiled brat etc etc") and also that I have the vague feeling that people just do things like this for each other and I missed out in a major way when I needed much more kindness than I got.
