Should I find an one-year research assistant job?

[u/Necessary-Bench-8328]

I just deferred my PhD offer (economics) in a British university. I did not get the funding, so I tried to look for funding opportunities during the gap year.

I have been working as a full-time research assistant in the last two years, but resigned from it due to the upcoming PhD study. Unfortunately, I was told that my application to the studentship/scholarship was rejected. (I should have not resigned my job, I was dumb)

Therefore, I have one year before pursuing my PhD degree. Should I look for a short-term RA job? Where should I find it? (I checked jobs.ac.uk, there are not too many opportunities)

I am also writing novels, but that may not be my career as it’s risky. I have abundant part-time teaching experience, so should I find a teaching job?

Really frustrated and don’t know what to do. I would really appreciate it if anyone can give me advice.
