Boundaries are about where you end and other people begin. If this line is unclear to you, can you imagine the ambiguity and enmeshment that may creep into your relationships?
Setting boundaries begins with identifying values and then living by these values. It is about maintaining control of yourself and making thoughtful decisions that benefit your overall health and safety.
It does benefit us to help someone else, and this is not a bad thing. Psychologists have identified that altruistic behavior has a secondary gain of feeling good about oneself for contributing in a meaningful way.
However, it can become problematic, if we sacrifice too much of ourselves in the pursuit of helping others. This is where boundaries come into play. Set healthy boundaries with others in order to maintain a healthy balance in your life.
