Sounds like you've already been through a lot.
You're right it would be hard to do tx with two teenagers at home.
Unfortunately hep C is indiscriminate. Yes, alcohol can make it worse but hep C can destroy the liver of the otherwise healthiest person, or not.
Your viral count is not relevant. I'm really tired of saying this but viral load does not equal liver damage. I had ESLD and a viral load of only 750,000.
So forget the numbers.
The biopsy will be the determining factor about whether you should do tx now or wait. Hopefully, you can wait for a few years, for better treatment options.
