You misunderstand and misuse some of the basic principles of Codependents' Anonymous.
Putting "the oxygen masks on oneself first" means we must take care of ourselves so that we will be able to have a self to help others with. Codependents take care of everyone but themselves, they are self-neglectful yet seek to control others. We all must be self-caring and self responsible first, no one is responsible for meeting our needs but us; only through being self compassionate first are we then able to relate to others as someone who can care for and be compassionate for others.
