These stories are always heartbreaking to read. I also have a chronic illness myself, and also had a family member with a similar (in etiology) autoimmune condition, but her case was one of the worst possible due to delayed diagnosis.
Throughout my childhood, I was forced to become accustomed to the constant sound of ambulances pulling up the drive, screams of pain, not knowing if my relative would live to see another day (as her disease eventually started causing organ failure) witnessing the aftermath of failed suicide attempts because the reality of her condition was too much for her to handle, and so much more.
I saw the ugly truth that was hidden from me in all of those optimistic success stories about "fighters" who don't let their illness win- and that was the reality that some people don't ever get better no matter how badly they wish for their body to be healed. From my early childhood and into my teenage years, I witnessed my relative deal with extreme weight gain from treatments that caused her to lose her marriage, infertility caused by a comorbid condition, breaking and dislocating bones constantly because they were so brittle losing her career, her house, all her friends, her dreams, only kept alive for years by treatments and surgeries that were forced upon her by others- all while having no quality of life at all.
Her pain was so great, I finally understood when I became an adult why all of those ctb attempts happened. She was living in hell. Yet everyone around us was always convinced she would get better somehow, even though there were no curative treatments available for the severe, rare form of the disease she had. All the false hope ultimately made it so much harder to watch her screaming and yelling and breaking everything in the house once she got out of her wheelchair, because she knew it was all futile even when no one else believed her.
Now, I finally understand all of this myself after years of incurable chronic fatigue, pain, and neurological symptoms. That sometimes there are no happy endings. That symptoms exist which can mystify doctors, can wreck your entire life, yet others may not even believe that you're truly suffering because they believe sickness is either cured, or kills you. They can't fathom what exists between those two extremes- the non-fatal, lingering pathology that accompanies one until the day they die. A special kind of hell.
