Dear OJB,
Living with alcoholism can easily lead to negative long-term effects for yourself and all other family members. You are wise to be concerned. As suggested, Al-Anon is a tremendous resource, and I would encourage you to investigate a meeting or two just for the insights they could bring. Also, you may meet others there in situations similar to your own. The network of knowledge and support has been critical to my own success as the mother of an alcoholic.
OJB, you can not change life at home, and I sense that you already know this. You can, however, change your response to it.
Congratulations on your studies, and best wishes in both regards. My thoughts and prayers are with you.
Peace,
Granny
