Well alcohol is one of the best for anxiety. But like you said it just masks and buries the situational issues. In the long run even drinking won't keep them at bay forever. Trust me I have a lot of experience is this area years ago. I don't think I would be so quick to label yourself an alcoholic.

Do you have a therapist. Therapy, yoga, meditation, exercise can all be very effective for anxiety. Therapy can resolve the issues that are bothering you like your Dad. Maybe not resolve but help you deal with it and grieve. I am sorry about your Dad, that has to be really hard. Yoga and meditation can be healing without saying a word. Meditation is simple but very difficult. You have to practice a lot. It keeps getting easier. If at first you notice how much "monkey mind" you have then you are making progress. Don't judge or fight the thoughts just watch them float by and gently bring your attention back to the breath. Every time you notice you mind has wandered just gently bring your attention back to the breath. over and over and over and over.
