When Margaret was suddenly widowed she was grieving and felt totally overwhelmed by running the successful winery that had always been her husband’s domain and being surrounded by wine.
She became dependent on drinking for a short while because she found some 'me" time when she drank some of the wine she was surrounded by. This did become addictive. She is very well now.
People who are very stressed often look for some “me” time or a “safe place” with a drink or cigarette. I really enjoy a game of solitaire on my IPad as a quick form of relaxation but I recognise that this can become addictive if I am over tired.
I have worked with several professional people like accountants and lawyers who used alcohol to relieve the stress of their every day life until it got out of control putting enormous pressure on their families as well as themselves.
Stress needs to be managed. It is like filling up a balloon; if you keep filling it more and more without releasing some regularly it reaches bursting point. You do need to be careful what you choose for your release mechanism, make sure it is safe and use it in small amounts often.
