Just found out my Hodgkin’s lymphoma is “unfavorable”

I had a consult with a radiologist on Friday, and at some point, it was mentioned that my SED rate was high enough to put me in the "unfavorable" category (103, I think it was), which surprised me. Up until that point, I'd thought that this was really no big deal, that as far as cancer goes, my kind is one of the least scary ones and I'd have to get chemo, but after that I'd be just fine. When I tell people that I have cancer, I also tell them right up front that I'd probably stand a better chance of dying if I was otherwise healthy and caught the flu than I have of dying from this. But what I'm really afraid of isn't dying, it's having to keep living with a significant health problem. I've spent most of my life being pretty healthy, so this is a big change for me, and I don't like it. I've been looking into moving out of my parents' house and into my own apartment, but if my cancer is likely to come back, that's probably not the best idea either for physical or monetary reasons (I have autism and am on SSI, and my parents are perfectly happy to help me as much as I need for as long as I need, but I really want some independence). Basically I think I'm really having trouble adjusting to being sick, and accepting the fact that it is likely to be a long-term thing.
