I would say support is necessary for me. I need to be accountable to something/someone external to myself. Whatever the something/someone is, that is up to you: God, sponsor, friends in sobriety, preferably a combination. Generally, I think romantic relationships and family are too close to us to give us the kind of objective support we need, at least in my experience. The first step is not admitting you have a problem; the first step is asking for help, and you are well on your way. Good luck.
