Highly suggest reading the book Boundaries by Drs. Cloud and Townsend. Or any other book on the subject. If you don’t like reading, watch some videos from experts. If people are treating like a punching bag and you’re calling them friends, sounds like you have a need for some strong boundaries.

Not the same story at all. But my mother has NPD and I had zero understanding of boundaries or self worth until I was in my mid-20s. Learning about boundaries was life changing for me. I cannot recommend them enough.
