Spirituality is not about becoming the person that you are supposed to be, or about doing the "spiritual" thing. To be spiritual is to compassionately welcome your truth -- what you actually feel -- whether you like that truth or not.
The cycle of overeating and obesity can be broken. Those trapped in it know what it feels like, but putting our heads in the ground and wishing it would go away will not work -- anybody who has lost weight only to gain it all back and then some knows what I mean.
Life is a journey meant to share with those close to us, and if we want the quality of our daily experiences to be as good as they can be, we need to decide who is most worthy of sharing our life with.

A relationship doesn't have to be romantic to fall into the "toxic" category. Many friendships, including mother-daughter and boss-employee qualify. If someone is bringing you down consistently, chances are that your relationship with him is toxic.
If one person has done something such as become healthier, develop new interests or changed what s/he wants in a friendship, then the friendship has to change along.
