yes, I have experienced this many times and yes i find its more painful when you know that person wants to help and cares about you.

btw i have had some success with my conflictor when i explain how i feel and what i need. sometimes it makes her annoyed but if i just try to be clear at least she knows what will help. And i try to accept the help she does give. It feels nice to know that someone cares about you.. like giving you a useless flower.
