Hi, Jason, and welcome to the forum. Please accept my belated condolences on the passing of your father.
I think you are wondering if you should again have treatment, considering what you went through before. Have you seen a GI doc or a hepatologist? You really should see one of those to discuss this matter. I was diagnosed with hep C in '93 and tried the interferon treatment twice. The longest I was on it was about 8 weeks. My white count plummeted so fast and so low that my GI doc took me off of treatment. After that, I went along w/o any problems except fatigue (and only being able to work PT) until 2005 when a routine ultrasound revealed a large cancerous liver tumor that had metastasized to the inferior vena cava. Following that, I went to Mayo where I had numerous MRIs, CTs, blood work, etc. They saved my life with treatment and surgery. Now I'm at a point where I have to decide if I want to try the combo treatment. After blood work and a CT scan next month, I am meeting with my hepatologist to talk this over. I have met with her a couple of times before, and she told me that the most common genotype (which I think you are calling a "strand" but maybe mean a strain) in America is genotype 1. It is also the most difficult to treat. They did testing for my genotype a few months ago, but I never learned just what it is. I will find out when I see this doc next month.
Since you had such an awful time with treatment before, I know you are wondering if you need to go through it again just yet. This is something nobody here can answer for you. You need to discuss it with a specialist. I can tell you that my hepatologist told me that they now have drugs to counteract a lot of the side effects, including low white count, nausea, and depression. However, everyone I have known who has had the combo treatment has said it was pretty awful. Since I am now 65, and am just beginning to feel good again, it is also a question for me as to whether I want to put myself through a year of treatment. If I don't do it, I risk liver failure and recurrent cancer, which would require a transplant. So I'm hoping my hepatologist will help me in deciding what to do. In your case, I would write down all your questions and go see a liver specialist to discuss treatment as it pertains specifically to your case.
Do read through the old posts and get info online at reputable sites such as the American Liver Foundation.
Best of luck and please do post again.
