Digital addiction in ME/CFS. Cause or symptom?

I have ME/CFS and use my phone (YouTube/Spotify etc.) 10 hours a day. When I don’t use it for a while, the cravings become extreme and physical. Stomach pain, head pain, intense anxiety, and severe brain fog. If I push through, I crash. My phone feels like a pacifier for my nervous system. I don’t get much pleasure from it anymore, it just keeps me functional enough to exist. So I’m wondering: Is this kind of digital overuse worsening my ME/CFS, or could it actually be a symptom / coping mechanism for neurological dysfunction? Has anyone else experienced crashes or worsening symptoms when trying to reduce stimulation?
