Don't be too hard on yourself IPWML, it is really hard and really daunting at first, especially if you are getting over a relationship breakup. Realising you are an alcoholic is definitely not one of life's pleasures.
It does get better over time, very slowly sometimes but it does. At least it sounds like you have a supportive family.
Just take it one day at a time that way it is not like a bereavement
All the best to you IPWML
