Kat, I have brought over a couple of our educational threads. You will find them now near the top of Page 1. Read The Stages of Liver Disease. That will give you a better idea of where your husband is at.
Given his other problems, I don't know if he would be a candidate for hep C treatment. Is he seeing a hepatologist? You need to ask what they plan to do for the hep C.
Ascites, or fluid in the abdomen from liver disease, is causing the bloating and slight swelling in the feet/ankles.
He's depressed because he feels lousy. Hep C causes a person to be very fatigued all the time, regardless of how much one sleeps.
The best thing you can do for both your husband and yourself is to read the threads here and learn as much as you can. The American Liver Foundation (americanliverfoundation.org) is also a reliable source of information.
Has he filed for Social Security Disability yet? I suggest he do so, or you can do it for him. It sometimes takes awhile to get it, but when approved they will pay from the time he first applied. Depending on the family's financial status, he may be able to get Medicaid. If approved for SSD, he would get Medicare 2 yrs. after when he applied for the disability. If he is approved for SSI, he would get Medicaid immediately, but also may be able to get Medicaid now. SSD is for people who have enough work credits, while SSI is for those who don't.
I know it's easier said than done, but try not to worry. That's just a waste of energy and is nonproductive.
Hugs,
Connie
