Looking for 1–2 practical books on setting boundaries and people pleasing (no motivational)

I’ve realized I struggle a lot with people-pleasing and weak boundaries.

I tend to be overly available, avoid saying no, soften my opinions to keep people comfortable, and give more than I receive in friendships and relationships. I often suppress anger or discomfort until it builds up and then either explodes or leads to me losing people.

I want something practical and honest books that explain why this pattern happens and how to actually change it in real situations

I started reading books recently.
