i think i've decided to stop caring

Grew up just always thinking of what people think of me and how to please them. When asked to describe myself I get stuck. Should I say the things that'll make them like me? or just who I actually am, and not care? I was a people pleaser who offered to do things for people I knew that I didn't feel comfortable doing. I was the person that did things out of comfort just because they encouraged me to do it. I cared and checked up on people who never reciprocated those actions/feelings back. I felt drained every day.
