You need to decide that you are worth trying your very best. You are worth your own effort. You deserve nothing less than your best. And then damnit hold yourself accountable to yourself. Ultimately it's your decision making that's rough ridin' it all up. Maybe you think the end goal is soooo big you get overwhelmed worrying and give up and give in before you've even gotten started. Just think about the first step, getting sober, and do that. Then, while you're doing that, think about the next step. Consider options. Research stuff. Get exercise. Pray. Then, make a decision, and push on trying your very best. If you do that there is no way you can fail.
