Dealing with Chronic Migraines and Mental Illness

How do you deal with chronic migraines and mental illness? Yesterday, I had the worst migraine that I’ve had in 6 months. I spent the day lying in bed in a dark room with sunglasses on and my eyes closed. The room still felt too bright, so my boyfriend covered all the windows with heavy blankets and jackets. He also literally had to spoon-feed me broth because I couldn’t open my eyes to see my food but needed to eat something to take my meds. My hearing got messed up and my ears felt fuzzy and started ringing. It was truly hell. I suffer from several mental health conditions, and all of this caused me to break down. I became irrationally scared that the pain would never end and actually started sobbing. The feeling that I had no control over my body triggered my PTSD. I even had some intrusive suicidal thoughts (all of which were passive and I would absolutely never act on). For those of you who struggle with mental illness, how do you manage it when you have a migraine? It’s like all of my normal coping skills go out the window because I can only think about my pain.
