I know a thing or two about self sabotage. In fact, the sad thing is that almost everyone does. Self sabotage is when you consciously or, most often, unconsciously follow an action or choice by which you are essentially betraying yourself. These choices are in the detriment of your physical, mental or emotional health. It may involve boundaries, it may involve doing things you know cause great stress. It may even mean going back to a toxic ex or friends, out of the wrong reasons.
