No one can tell you how to live your life Marit. That is completely your own choice.
But look at what has just happened. If anything it's a classic example of what happens from the point of everything going great, descending into the point of taking a drink.
Try to recognise that pattern of events and look for ways to break that cycle. You can do that by developing a plan of what to do at each stage of the cycle. Examine your behaviour and ask yourself, at what point could I have approached this differently or what could I have done at this stage to stop the usual reaction
When something bad or unforseen happens it doesnt have to be inevitable that it ends up in you feeling you need a drink...look around the site for information on how to deal with such situations and put it into practice when you recognise that feeling coming on
Things happen when we drink, every one of us on here have done things we regret. Your relief from the guilt that you feel rests in the effort you put in to making sure it doesnt happen again.
