Hi CB -
You are me, 2 months ago. It gets better, but it's not a straight line.
I'd recommend you make contact with a medical professional, or at least a substance abuse counselor. Also, get your local AA schedule, and reach out to someone in the meetings. I'll admit to not liking AA very much or all the time. But it's great for what I call "the mechanics of sobriety" - how to get through withdrawals, how to relate with people who still drink, etc." You can start there and then see how you like the rest of it.
I also used to be able to stop for a few days and feel fine...until all of the sudden I couldn't. Coming to terms with that, in addition to not picking it up, takes some reflection. definitely keep hitting up your dad for advice.
