If 2pm tomorrow feels too far away just focus on the next few hours.
What kind of things on your laptop are helping at the moment? I quite like the site games for the brain it has quite a few short games and most of them don't have a timer so it doesn't matter is I zone out for a bit. I also quite like online jigsaws but they can require a bit more attention depending on the number of pieces you go for.
I meant plan quite loosely like have tv on or play games on laptop, keep occupied, sit quietly, make a cup of tea, surviving in 5 minute chunks.
I'm glad that you have some support whilst she is away, I appreciate it must be difficult to talk to someone you don't really know though.
