Ryuiichi,
I am willing to do an interview if it will help you, though I have to admit I am no longer in depression (and no plans getting back to it
). Feel free to contact me if you think I can be of any help.
What I can tell you from my experience, is that when you are depressed you are usually not keen on having interviews, you are not interested in anything. The loss of motivation and interest is one of the major symptoms of depression.
But feel free to contact me, whether for your project or anything else.
Erik
