I used to be just like you Eleny. I am still a people pleaser sometimes. But I used to take on the energy of the people around me, whoever I was with. I'd conform to them, because I didn't like myself enough to show my true feelings and thoughts. I pushed those down so not even I myself knew what I really thought and cared about.

I'm not sure what exactly changed for me. I got older. I find that the older I get, the less I care what people think. I'm 33 now. I still have my moments, but it's nothing like when I was in my 20s or teens. I wonder if journaling your thoughts would help you. I'd also like to recommend 2 books: Self Compassion by Kristen Neff, and The Mindful Path to Self Compassion (I forget the author).
