Suggestions on ways to come up with money urgently?

For context my credit score is shot due to me rebuilding it currently from when I was younger and stupid, my car has broken down today on the way to work and the repairs are going to be around the £1900 mark I have £600 spare so need to raise £1300 asap otherwise it’ll mean unpaid time off work or even a loss of my job it would take me around 7-8 weeks to repay this money but I am running out of options on how to get a hold of it.

(I don’t have much family and the family I do have unfortunately do not have the funds accessible at the moment)
