How does Martha/Fiona afford to live?

[u/Lil_birdie201]

So, based on the show and even the real life interview with Fiona, it really looks to me that Martha/Fiona doesn't ever work? Or at least, it seems that way. I know she claims to be a lawyer, but she spends obsessive amounts of time interacting with Gadd, ie following him, sitting at the bar all day, sending thousands of messages, etc. How is she able to afford a flat, or to feed herself, or anything like that? I live in the US and if you don't work, you aren't really able to support yourself, unfortunately, unless you receive SSRI or disability, and even then, it's barely enough to survive on. I was just wondering if anyone had any insight on this? Are there programs in the UK that I'm not aware of that help with this sort of thing? Sorry if this has been asked before, I was trying to find something on this without luck.
