I experienced severe anxiety and depression 4 years ago, did not know i had hbv, i came to know about my hbv infection last year (February).
My anxiety was triggerd by certain stressful events, anxiety led to depression. A book by Paul David "At last a life" pulled me out of dark place.
I used to feel very weak, i am active cyclist, could not cycle for almost a year.
I started taking entecavir in February. Currently i feel good, though anxiety and depression visit me, they do not last long, Paul's book has taught me a lot.
I think any chronic illness (whether you are aware of it or not) may be causing depression, as our body doesn't feel healthy, this sets in a low mood.
A good diet, exersice, medicine and awareness will help live a depression free life.
Currently i do cycle regularly, need to improve my diet little more and give up one addiction that i have.
One has to accept and learn, that way things will become easier.
