I think that co dependancy is term that if you take everybit of info and all of the symptoms too literally and consume yourself with the everything co dependency entails you will only make yourself upset. I beleive that every person in the world has co dependant characerisitcs. It is just that some have better coping skills than other as they live their lives. If you are feeling like this is something that is a significant stressor for you and it is preventing you from your daily function in life you should consider treatment. There are support groups called CODA that you can become involved in. If not individual therapy would be a good place to express your concerns.
