Perhaps you should read "The 48 Laws of Power" by Robert Greene. I first read it in my early thirties and got depressed for a while. I used to be 'people pleaser' too. Expecting everyone to do the 'right' thing or reason in a certain way. That book made me understand that people may be guided or driven by laws or maxims different from mine. I had been very naive about how the world worked for so long and that made me sad. I certainly wasn't going to court attention at all costs, or keep people dependent on me, but I was now aware that these were principles followed by some people and expecting them to behave otherwise was foolishness. Then learn some Stoic philosophies. The daily stoic by Ryan Holiday is good recommendation.
