Thanks for sharing your story and I understand that it is a lot to process at the moment. The lab results suggest that your have been exposed at least 6 months ago and you currently have a chronic hep B infection.
It is not a cause to worry about your life being painful and short. Many of us here on the forum have chronic hep B and we live close to normal lives with no ongoing pain.
It’s great you have booked an appointment with the hepatologist and will get more tests done, that’s the right thing to do.
The anti-HBs <10 means you are negative for it, so you are right that it means nothing because the HBsAg is positive. You can learn a little more about what each test means here: EXPLAINER: Lab results and their interpretation
Hope this helps,
Thomas
