She does seem to be struggling with lockdown so if she has the means to rent somewhere else to improve her mental health she should. But she didn't have a job that took her out the house every day before lockdown so it's not a massive change for her.she's clearly struggling with lockdown though so having an external office is probably really helpful for her mental health just to have somewhere to go that's not the same rooms in her house. As much as lots of people are excited about WFH taking off because of covid, plenty of people also like the leave the house for work
She does have the luxury of having a massive house with plenty of rooms to seperate parts of her life. My work set up is on my dining table, in my lounge, so is always in my sight. I find myself going to bed really early just because I'm sick of being in the one room all day long!
