Please don't regret telling them at work - that may well have helped you to clock up 5 sober months (which is brilliant, by the way
)
I agree with Yankee, you could be judging yourself too harshly and imagining that others are doing the same.
I know it's tough to miss out on a promotion, but being promoted before you're ready can be a nightmare. Now that you're sober - and have proved to others that you're sober too - you're in a much better position to grab any opportunities that come along.
And if others are looking at you strangely, maybe it's respect that you're seeing? Or jealousy, perhaps, because you're proving that you have the ability to identify a problem and deal with it
As Sasha says in her lovely post, go get 'em, Tiger!!
