We've all been there man. There's a way, many ways, out.
I think, honestly, it's important and true to see yourself as someone who keeps trying to get sober, rather than someone who keeps "failing". There is something within you that wants the sober life - you have to honor that, focus on it, heal it, use it, and eventually you will be able to fully access it.
Good on you for coming here and posting. Gotta get sober. Time to get to work.
