I am always giving wayyy too much of myself to other people, in hope that they will love me, appreciate me, and think I am a good person. This means that I am always prioritizing other people before myself, but under the surface, I get resentful if people don't give me back what I want from them. I want to fix this issue, but I need somewhere to start. Do you know any good books, videos, etc, on how to start prioritizing myself more, and stopping myself from giving too much of myself to other people, to value myself more in a sense.?  Currently reading "No More Mr. Nice Guy" and it's amazing!
