I am so sorry you are suffering as well. Chronic pain is a layer of hell most people are blissfully unaware of until their twilight years. Few can understand the nightmare that is enduring years upon decades of unrelenting illness. I have been sick since I was around 17, and it seems to get worse with time.
I am only 22 and suffer from permanently distorted blurred vision, chronic pain in my legs, feet, back, head, stomach, and hands, horrible IBS, chronic fatigue syndrome, chronic low grade fevers, brain fog, raynaud's syndrome, and tmj. I do not receive any pain relief for any of these dehabilitating conditions.
I wish none of us had to experience our bodies torturing us. Even as I'm typing this, there's a stabbing, hellfire sort of pain behind my eyes and it makes me want to scream.
