I wouldn't think like that. I have made enormous progress in the last 7 months, basically came back from death's doorstep. Nowadays I am at least 70-80% better than I was, which leads me to believe that in another year or two of taking care of myself I should feel like superman. Being though you are still young, your recovery should be even more rapid.
Just remember: strict diet; the supplements I and others listed above; raw garlic; warm water enemas; sauna sweating; and tons and tons of a wide variety of raw vegetables.
