One thing I have discovered since my OH's diagnosis last July, and since finding this brilliant site and reading about peoples' varied journeys is that there isn't a 'normal' and everyone is different. Some people waltz through HT with virtually no side effects (my OH) and others suffer from hot flushes and fatigue and weight gain. Some blokes feel ok physically but have a really tough time psychologically / emotionally, and that of course has an impact on their overall health.
It sounds as if you are feeling ok physically, but maybe things are more difficult emotionally? After all you have only had a month to start coming to terms with this life-changing treatment and presumably not much longer to come to terms with the diagnosis. Brilliant that you are doing so well but it would be odd if you weren't at least a bit knocked sideways by it all.
Either way, well done on handling things so well - 'ok', 'sort-of ok' or 'ok-ish' are pretty impressive at this stage I reckon.
