Tytan,
Your remark about not being able to just enjoy a glass of wine with dinner and hoping someday you might be able to again...made me think of something a friend told me earlier this year when my s**t was starting to hit the fan and I was waxing nostalgic....she said "adjust to the new normal"
I urge you to follow your instinct to write, I've written a number of books, it's an amazing way to learn about life,yourself and your subject matter. I find it nearly self indulgent to write...because I get so much out of it.
