You may only make a BP once, but surely you have to honour it many many times over, every time you hear the AV in fact?
So what is to stop someone making it, and meaning it at the time, but then failing to honour it in the future? In the past this is what I've done, repeatedly.
This time I have just basically realised that I either stop for good, or I'll keep going round and round the addictive cycle, and there's too much at stake. In the past I've never quite accepted this, always thinking I can continue to dabble - to the point where it's quite illogical that I could believe that but still I did. I've been feeling huge amounts of grief/sadness at this decision/realisation that it's 'over' (or, my beast has) more so than ever before which makes me feel like maybe this time I'm actually serious.
