Hello there!
I played an inordinate amount of WoW and I loved being in that world...hundreds of days played on my timer.
I don't play anymore, sometimes I miss it, but not often. I have a son with autism and two other children and they keep me busy.
It took me forever to get my bachelor's degree. Online classes worked for me, especially one at a time. The online classes had a very specific format so the individual instructors mattered less.
One thing that has helped me is to create a story in my head and work on that. Occasionally I type some of it up, or if an idea pops into my head I write it down, but mostly just build the story in my head. Originally I thought of the story as a sci-fi fantasy about someday being able to communicate with my non-verbal son, and I borrowed elements from other stories, like Tron, but lately I have been slowly eliminating the "other story" elements to make it more and more my own story.
More recently I have been working on a YouTube channel about my son. My daughter loves to draw and I am working with her and hopefully someday she will be able to draw some pictures from my fantasy story and we will make videos of that too. In doing that, I hope to learn more video editing and teach her how to do it and that might help her further her skill set.

What worked for me was to just keep trying, poking around, exploring different things until I found something that could replace WoW...build my real-life character...work on my real-life character skills...like I used to enjoy in WoW.

I think that it is very good that you are here to talk about this issue and want to figure out a solution.
