I think that to a degree, we are all co-dependent and probably always will be.

I think the biggest thing for me is when I can't tell the difference between what is my responsibility and what belongs to someone else. If I take on that which is not mine, two things happen. First of all, I jeopardize my own mental health and serenity. Second, when I step in to fix/rescue/help another, when they are able to help themselves, I am depriving them of valuable life lessons.

It is sometimes very hard to make healthy boundaries and it is a very individual thing. I don't think its necessarily wrong to help another person, as long as they truly need the help. I also have to look at my motives; why do I want to do this? Am I looking for approval? Do I feel I need/should do this for the other person to love me? Etc., etc.

Just my opinion; take what you like and leave the rest
