The majority of hbv-ers live a long and normal life. But it is very important to monitor our hbv status through regular tests with the help of a good hepatologist (not a family physician). And I think it's good to educate yourself about this disease as much as you can, so you can make informed decision about treatment when you need it. Like stef2011 said, this forum has a lot of very good information and the HepB Introduction & Welcome Page is a good place to start.
If you are doing these already, try to enjoy your family and life and don't let the worry get the best of you.
having hbv is nothing to care about in particular, just remember to check liver damage by fibroscan at least once a year and hbsag quantity in iu/ml, so if you can afford treatment and hbsag low you can clear it by interferon or sequential tenofovir+peginterferon
in the forum you will find all needed to know about hbv which can be much more benigne if controlled than other viruses present in everybodies blood like many retroviruses, cvm, hpv, herpes viruses, all present latent but present
