Yep, same here. I was bullied a little in school, but have always had issues with self worth and feeling like people want to use me, even though it has rarely happened in my life. No clear reason why I have self esteem issues that I can pinpoint, so I think maybe it's just "normal" and shit that everyone struggles with at some level.
I can also relate the OP and want to please and impress others. I have a strong aversion to disappointing other people, but I also feel as I'm getting older I am becoming better at drawing that line and giving less fecks. It's a work in progress.
Bro, I think I speak for everyone here in saying we all want to use you.
