Hi and welcome! I'm sorry to hear that work is so unfulfilling for you. :( That's a really hard place to be, caught between the need to make a living and unrewarding work.

Fun with fanfic is good, and I consider it time spent writing! And yeah, social media is quite the time suck. I mean I guess it would be nice if I could be productive every minute of the day, but sometimes between tiredness and just wanting to zone out for a while, scrolling through my dashboard all I can manage.
