Thanks, Susie!
Yes, I feel very fortunate. I definitely feel like I need my weekends off from it, though. Yesterday, I did some extra work to make up for some time off I'd had during the week for some appointments. I planned to spend most of Saturday working, but by 3:30pm I'd had enough. But to be fair, I was testing some seriously horrible stuff to do with death, which got tiresome after a while. When I can, I try to focus on things that make me laugh, but that's not always possible.
I do wonder whether I might need to set aside some of my money for a few therapy sessions at a later date. But also, I always have access to the non-harmful version of the project if I ever want to take a step back for a bit. And our supervisers have said that it's fine if we need to do that.
