Hi and welcome!
1. Alcohol being good for you...They also used to say tobacco was good for you...especially the lungs...alcohol is bad for your health and I have a funeral to go to tomorrow that proves it.
2. In early recovery it is typically a good idea to avoid dangerous situations. If there is a situation you feel you must attend try to prepare for it. Have an excuse ready...try to come late and leave early...try to always haves non-alcoholic beverage in hand...people are less likely to pressure you to drink booze if you already have a drink.
3. One tool I found helpful in these situations is to spend some time prior to the event de-romanticizing alcohol. This involves remembering in exquisite detail my worst moments...ie. the way it feels to barf up a particularly nice glass of red wine...doesn't taste so hot on the way back...does it?
4. Don't expect others to support you...they have various reasons (mostly selfish) to think you are not alcoholic.
Good luck and stick close to SR it really helps!
