Like DreamCatcher said, being honest with yourself is the only way to start your recovery. It was really hard for me to admit I was a really awful person for a long time. Nobody wants to admit that about themselves and it's really easy to blame others. Focusing on what about drinking is making your life less desirable then it should be can be your motivator. For you, it appears your health is taking a dip because of it.
Who besides you in effected by your health? Family? Friends? People who count on you? Addiction isn't a selfless disease, your choices and behaviors also negatively impact others. This feeling is also what brought me to sobriety, I'm tired of hurting the people I care about.
Good luck, and use this place for support. I come here every day, it's part of my routine. It holds me accountable and a fresh morning reminder of the positive in my life.
