First of all, Happy Birthday!!!
Sometimes it's good to rant....it's certainly better than reaching out to what (who) you know will burn you. I think sometimes us codies allow the dysfunction in our lives because it takes the focus off of ourselves and our world is consumed with the drama of life with an alcoholic. At least, I know I've been guilty of that.
Do something special for yourself for your birthday. Buy yourself a present, get your nails done, get a massage....treat yourself, because you're worth it.
