I think you'll find introverts overly represented in an online community such as this. I don't do face to face support because that would have been draining to me. If I ended up needing it I would have done it. I don't interact all that much in IRL outside of work and a few friends. I enjoy my downtime.
I wouldn't call that isolating though. This fall I had a few months when I was isolating meaning I wasn't having conversations with others and my mind was starting to knot up. Logging in here fixed that.
