(((((((Namommy)))))))) I'm really sorry you're going through this, but you will get through, and you can get through it without relapsing. It's good that you're doing what you need to do - just hang on for the ride, as unpleasant as it may be, and it will pass.
Gooch has some excellent suggestions above for dealing with the headache. Lying down in a dark, quiet room and using a cold washcloth on your forehead can also help with migraines. There are quite a few non-narcotic meds for migraine now, including a fast-acting nasal spray. If you feel like your doctor is blowing you off, it might be time to look around for a new one when you're feeling better.
Hang in there, Namommy - you can do it, and I'll be thinking of you.
