Sorry you are having such a tough time OP
Being stuck in the same environment drives you potty.
Someone upthread suggested and I agree trying to break the day into chunks is a good idea.
A few hours, or however long you can manage of sitting in one chair watching tv. Moving to the sofa and catching up on MN. Move again to read or listen to an audio book.
I always suggest cross stitch. I have got quite a few people into it when stuck recovering. It doesn't require that much thought and kits are pretty cheap. Just gives you something to bypass the boredness threshold of your brain.
While eating nutritious food is excellent for recovery- a few treats are needed too. I usually try to have really nice "good" food like mango or raspberries. As well as a bit of chocolate. I can usually eat my weight in crudites and hummus as well
I make sure to be well hydrated especially when on serious meds like morphine.
Morphine and steroids are the two medications that absolutely mess with your head. Tapering will help loads, even though it may feel horrible it will be much better this way, as youve already found out.
Im sorry you have had to find out the most awful way about how friendships are a bit fickle. Maybe some of these will be recoverable. Some people are just shit around illness. Nothing to dwell on now - but if people are special to you let them know when you are better.
DH could be an arse, or he could be struggling- not for me to say. Mine has been both over the years when I have been ill.
I am also an avid reader and struggle a lot when im ill. I usually end up rereading old favourites, then it doesn't matter so much when I get hopelessly lost.
As you seem to be a fan of hospital stuff House MD and ER are both on Netflix and have tons of seasons.
Also Schitts creek, 30 Rock and The Middle are great mindless comedies.
So glad your physio has gone well and I hope you can get upstairs soon. A change of place will feel amazing
