Wow, I can relate to this so much. I know exactly how you feel when you describe this listless sort of endurance as idiotic. People always tell me to keep going in spite of there being no further treatments I could try for my problems, and I find that incredibly ignorant.
I do feel idiotic for continuing on when I just keep accumulating more and more illnesses over the years. Perhaps I could have dealt with this miserable life if I'd only had autism and ptsd.. but having chronic pain, CFS, IBS and other annoying conditions like TMJ and tinnitus on top of that makes my life not worth living at all.
People have good intentions when they tell us to merely press on in spite of the nightmare we have to recon with every day. However, their hubris does not allow them empathy nor for them to accept that for the vast majority of us, we will not get better. There is no magic cure on the horizon, for most new drugs take over a decade to be approved and the vast majority of governments will restrict novel substances so that you physically can't take your own risks and get your hands on them.
Normal, healthy people really cannot fathom what it feels like to spend every waking moment in pain. They expect us to just deal with it and get on with things, but what if I can't? The vox populi won't let you utter even a whisper about ctb.
All of the chronic illness support groups I've been on will ban you if you talk about being suicidal. The largest CFS group won't even let you post scientific articles about suicide-like how it disproportionately effects people with these sort of illnesses. Basically, if you express any sentiment that hey, this sucks, and I don't want to do it anymore, they will lose their shit.
How dare you don't want to be a strong warrior? We don't want to speak to a toxic person like you who doesn't want to help themselves! Go talk to a professional, life is worth it in spite of your horrible illnesses, because of good food, kittens meowing, and the serenity of a walk in the woods.
If you have multiple illnesses people REALLY do not understand. Sure, I liked good food, before I got horrible IBS and now I wake up every morning with my innards cramping and aching so bad I nearly vomit. I loved eating prior to literally everything making me sick. Walks in the woods are great if you have the stamina to endure it without horrible pain afterwards. All of these "little treasures in life" are totally inaccessible if you are disabled by illness.
I wish people could wake up and smell the roses. That for many of us, reality is not some heroic epic where all we have to do is slay a monster/find a cure and our suffering will be over. For a lot of us, there will not be a cure in our lifetimes, and we are meant to lie down and accept a subpar quality of life while our dignity is still intact.
