ya she sounds a lot like an older version of me. Trust me, you can only laugh something off or pretend everything is ok for so long. Deep with in her there is the knowledge that something is seriously wrong. For me the denial stemmed from that fact that if I actually acknowledged what a horrible monster I had become I truly felt like I would die. The denial was easier but in the end was killing me. The best thing you can do is stay away and protect your sobriety. In the end we all have to deal with our demons one way or the other.
That being said I know this is hard for you and I think its awesome that you had the ability to recognize there is a problem and get sober. Congrats on your 19 days!
