You've raised serious issues. There would be a question as to whether your husband would be a candidate for treatment. Certainly he would need to be psychologically evaluated and monitored before anyone would make that determination.
But you don't say whether you're considering treatment or what your current thinking is on managing his illness. The first step, if you have not taken it already, is to get a thorough evaluation of the state of his liver. That is normally done through a liver biopsy. If possible, your husband needs to be under the care of a specialist, known as a hepatologist, who knows how to work with people with HCV. Once you know the current state of his liver damage, then you can begin to think about treatment, which might involve some lifestyle changes or not. There are new treatments coming out in a few years that will have higher success rates and shorter treatment times. If he is relatively healthy, you'll likely want to wait for those. If he has a higher level of liver damage, then you'll need to focus on treatment and deal with the psychological issues now.
In the meantime, the most important thing is that your husband live a healthy lifestyle. He should refrain from drinking alcohol. If he is at all overweight, he should shed those extra pounds and get within the normal range of BMI for his height. Those are both steps that will slow down the progress of the illness.
Good luck.
ok don't believe in the ADD thing about your son. kids that young are hard to diagnose and you DO NOT want to label him and make him feel like he can't do things. make him feel like he's smart and better, and able to do whatever he sets his mind to.
about your husband. a lot of people here has been or are on antidepressants during treatment for hepatitis c. if your husband isn't on treatment for hepc, then there might be a lower correlation between the 2. sometimes life is all about attitude, think positive.
