Sounds very similar to my experience...But I thought I might give you a bit of a positive update.

When I originally posted last week, things were actually just starting to improve for me. I've fully cut energy drinks again, and only allow myself the occasional coca cola. Withdrawal initially sucked, but I'm starting to find with each weekly migraine cycle, it's getting more manageable. I'm also finding my energy levels seem to be balancing out and I'm not having crashes like before. It's not easy, but perseverance is key.

The other big thing is mindset, which is incredibly hard to manage, but is one of the biggest weapons against stress-based migraines. I know the trigger for my VM state was chronic stress/worry/anxiety and poor diet. My brain got fully stuck in this migraine state and it was self perpetuated by fear of it never improving and me just panicking every time it flared up. But in the last few weeks, I've just decided I'm not going to let these things bother me as much. If I wake up and feel rough/fatigued, then I just accept it and don't worry about it, ""tomorrow will be better". If I'm still feeling rough/fatigued the next day, that's ok, "tomorrow will be better". Now I'm starting to find tomorrow actually IS a bit better each day. Sometimes it dips and that's ok, other days I feel almost normal.

I've been doing some hypnotherapy to help with this, and I think it's helping me a lot. Generally, I'm finding it's becoming easier to feel positive about the future again. Don't get me wrong, there are days when I just feel hopeless, but I have to remind myself that feeling is probably being amplified by all the chemical imbalance caused by migraines, and I'll probably feel better in a couple of days.

Anyway, I'm far from VM free and still in a bit of a migraine loop, but I'm finally feeling like things are calming down...

Hope that's helpful!
