I think your best scenario will be to make plans to see your boyfriend outside of the UK and wait until you have a job to apply for a UK visa. Without strong ties to Turkey, such as a job, family you need to care for, etc..., and a tie to the UK (your boyfriend), you don't have a strong case for a visitor visa at this time.
In addition, if you apply again and are refused, you'll be developing a record of serial refusals, which could hurt your prospects for a visa in the future even when your circumstances are better.
I'd hold off until you have a new job and stronger ties; you'll have a much better change of success.
