Comparisons can be odious. Addiction is one form of hell, ME/CFS is another, there are many other things, all hellish in their own way. I think about women who are victims of sex trafficking and who would be killed if they tried to get out (or their families are threatened). I can't fathom that existence but it's reality for thousands of women. Life isn't fair. I do wish sometimes that the people who have power over our lives (doctors, NIH etc.) could experience ME/CFS for a month or so, long enough for them to start feeling panicky. One day wouldn't do it.
Though I do think I know what you mean. If someone is an addict, there is something you can do about. I know several addicts in recovery. They have full lives. And then there are other addicts who never make it and their lives are pure crap. And though it's tempting to say they should just go to rehab or something, I don't know what they go through and it's not my place to judge.
I know, if we had a choice, or something we could do to recover, I think we would all do it in a heartbeat, regardless of what it was to get our lives back. And ME/CFS is particularly hellish because we go through it alone and have to deal with skepticism and disbelief and bad treatment or just being ignored, etc. - it's crazymaking. I think
@Daffodil put it very nicely - like being in a coma, but only worse.
