Goog morning (JST).
Although your husband got angry when he knew the title of my weblog entry, the situation was similar also in Germany, right
Your idea of treating your possible depression in Japan has pros and cons as I have mentioned previously, so, you should be keep your coolness when you consider the timing and location of the treatment.
My view on your physical/mental condition has been a bit changed after a lot of Q&A. Now I don't think you have serious physcal illness (when can you know the result of the medical check you received in Germany this time?). Main problem would be mental one, maybe affective disorder.
But it still takes a couple of months - at least a month - for you to be appropriately diagnosed and treatment outcome is confirmed.
If you are not well prepared for that, you can come to Japan tomorrow, but I guess you re not. Am not I right?
In my opiion, it would be better for you to calm down.
