Someone close to me doesn't want me to get better

I've been in shock for a couple of days. Someone referred me to a doctor who practices lifestyle medicine (I'm in the UK so this isn't usually a viable route for us on the NHS). I discussed it with a family member and mentioned even if this is expensive, if it 'fixes' me, it would have been worth it.

Their reaction just shocked me. This person has been very helpful to me through crashes and illness which is why I was so taken aback. They said nothing is going to change if I get better, my hobbies are still reading and needlecraft, so why do I want to get better. I initially thought it was a joke and I said well who knows, what if I want to climb Everest someday. But then I realised they were serious as a heart attack!

I said you sound like you don't want me to get better, which is very odd as you know how much my quality of life has suffered. And they said yes, I feel like you are much more likely to become selfish if you have your health. Selfish...? Is it selfish to want to travel or have energy to hang out with friends?

I've been reeling for a couple of days as I always thought this person helped me out of love - they were the only one who I felt 'believed' my CFS when everyone else was trying to 'fix' me with turmeric IYKYK. It was always the dependency they liked.
