Chronic Migraine and Work

I hadn't had a migraine in 2 years when they started back up..in March. At first, the aura/signs were worse than the actual headache. Chest pain, shortness of breathe, etc. Had a full cardiac work up to rule out anything there. Since June, my migraines have been worse and worse. I've had 49 days with a migraine out of the last 60...and that's counting it "gone" when my pain is at a 2 out 10. 11 good days since June 7.

I'm on short term disability from my job, but that will end soon and I can't even fathom going back to 10 hour days talking to customers on the phone with the level of pain I'm dealing with. The last time I worked I ended up in the ER because my migraine became so severe.

I haven't been able to identify a trigger and I actually thought for a while the amitriptyline was starting to help but since we increased the dosage I'm back to pretty much daily and moderate (6/10) migraines. My FMLA is out, my short term will end soon too and then I think if I don't go back to work I will lose my job and my insurance.

I don't know where to go from here or how to make a living when I don't know if I'll be able to function and take care of myself on any given day. I used to be self employed on the side from my day job (and as a primary job at different times) but clients aren't likely to be understanding when deadlines are pushed back due to an inability to function.
