I have a friend with decently managed Bipolar II dx.

He is my pen pal. We exchanged emails almost daily. He writes very well and cana write succinctly. He authors a technical blog. I cannot comprehend his blog posts in detail, as I am not a software engineer, but even I can understand his basic points, a testament to his ability to explain well. His blog posts occasionally go viral. He is not always clear about what made this post viral, but that post played to mixed reviews. Blogging helps with his mental illness management, in addition to psychopharmacology.

I wonder if you can do the same on any topic of interest. This is just one idea and in no way do I suggest it is better than alternatives. But... Would it be fun for you? You can write confessional prose, book and movie reviews, cultural commentary and what not
