Did you ever think about blogging in addition to Facebook? In my experience people blog for a variety of reasons. I started blogging a few years ago because I just needed some interaction with people on my own terms, so I blog and I also actively read and comment on other blogs to build that circle and those relationships.
Some people blog just because they need to talk. They need to just get everything out of their system. They talk about their daily lives, their families, their sicknesses. You’re very creative and I know you’re going though a rough time right now medcially speaking but I think after a while of getting all of that out of your system in writing, you might enjoy the interaction with people.
I think you write well and I think you could be a good blogger! It’s not for everyone and I think about 70% of the people stop after a week but you never know, it might just be your thing.
