What are some GAL activities you can do from the couch? If you have a smart device you can download a language app and try out a foreign language. I'm thinking of starting to read poetry in addition to fiction when I'm home alone in the evenings. Pinterest has some gentle yoga videos that might be appropriate while you're healing -- I kniw for sure there are a number of practices meant to be done from your bed. There are TED talks, free online courses on all kinds of subjects, etc. GALing is the best aid to detaching there is.
I realize your options are limited at the moment but even just brainstorming your options is better than just sitting there stewing.
Good luck!
