It's about quality of life, not suffering as in "pain". It is very obvious you love your dog very much and have given her the very best life possible. Now it is time to do what is right for the animal. Perhaps you have a vet service which will come to your home and perform the euthanasia where she is most at ease and while you hold her. It is one of the most difficult things you will ever have to do but it is also the right thing to do and you will, in the end not regret having it done.
