I just want to take issue with your thread title. You can do this!
You put your sobriety first. Stop drinking, develop and execute a plan, and inc your head is clear and you have more confidence you can address your other problems.
It's a shame about your dad being that insensitive, but it is what it what it is. Don't give him the opportunity to say "I told you so."
You can do this. Get help, and make your other decisions with a clear head.
