moving back to the UK with an HPI visa and no further plan?

I lived in London for over 3 years but couldn't find work after my visa expired, so I moved out earlier this year. I've found out I'm eligible for another visa (for 2 years), and since my entire social network is there, I really really want to go back. Beyond my friends, I feel at home in the city. I don't mind a house share and suffering from the blow of TFL monthly.

Now, I have an MA in English Studies + a recent publication in a somewhat revered journal. Otherwise, it's just been service jobs. I hear they're making it increasingly impossible to immigrate to the UK. I was hoping I could build something in the writing world in order to eventually apply for a Global Talent Visa, since I doubt I could find something else?

The more I read about people's experiences, and obviously having had to move out of the country myself, the more I question whether to try again. I would like to hear some honest opinions, or even success stories from people who were able to get sponsored with similar degrees.
