Rush, you came here and posted because you know drinking won't work. You know staying sober and getting through this with a clear head will work. I'm very sorry about your Dad's diagnosis. It's unfortunate that your family is moving across country and I'm sure you feel lonely. I was really lonely too when I stopped drinking because I had pretty much destroyed all my friendships. I lucked out with a volunteer position and it changed my life. Is there something you could do to give back in your community? It could be a chance to feel good about yourself and to meet new and sober people.
Please know that we are here for you.
