It was very hard for me to break the people pleaser pattern too...
and
sometimes I slip back into it as it is familiar
however
the longer I treat myself with the same respect I give other people, the harder it is to slip back into familiar behaviors

mama bear is a great analogy

protect yourself as much, if not more than you protect everyone else
we need to be as kind and accomodating to ourselves as we would be with other people

when we start to do that, people will respond

I teach my children and my students that people will treat us how we expect them too

it was tough for me to learn the lesson I was supposidly teaching
