Just think how much better, "We are so proud of you," sounds than does, "We are so sorry for you." Praise beats sympathy hands down.
I honestly believe you can do it once you decide it has to be done. Or not. It's up to you. If you need help from a higher power then reach for it. If you don't, then go for it.
It really is up to you and you've got people pulling for you. I'm pulling for you but I don't feel sorry for you. It's your choice. Go for it.
A friend of mine was drunk for 25 years. He sobered up and kept a bottle of his favorite at home. When he'd get down he'd pour himself a drink, look at it, and say, "Do I want this drink today?" Every time he would carefully pour the drink back in the bottle and say, "Maybe tomorrow but not today." He died sober at 84 in Hawaii.
