People pleasing is an addiction just like drug, food and alcohol dependency. The difference is approval addicts seek out people for their fix. People pleasing is at the core of every self esteem issue. The people pleasing, approval addict uses acceptance (or non acceptance) of others to determine their self worth and feel loved. The approval addict compromises or negates their own needs and moral compass. This behavior enables others to treat approval addicts like a doormat and the people pleaser, accepts it. And worse: believes they deserve it.
The first step to recovery is admitting you have this addiction. Once you own that, recovery from people pleasing can begin. Awareness of YOUR needs and making that your priority will slowly replace the need to please others to feel loved. You will begin to love yourself, and that is a wonderful feeling.
