Hi @Andrei,
Thanks for sharing your story and sorry to hear about your struggles.
To address some of the confusion, antivirals definitely prevent liver cancer and liver disease progression caused by hepatitis B. This has been shown across many populations in different countries - the reduction is not complete, but around 80%. There are definitely some people still at risk of liver cancer even if they are on treatment, but the risk is much lower.
I agree with @Bansah1 in talking to local groups about getting access to affordable treatment. If you are in the US, there are also ways of accessing affordable antivirals through cost plus drugs - Possible side-effects from antiviral therapy - #129 by PuallyHBV
