Should I pay for the LPC myself?

I graduated with a 2:1 from a red brick uni but got a third in my first year, despite having mitigating circumstances. After two years of applying for training contracts should I accept that my first year results are a bigger barrier than I first thought? And given that we’re in a recession is it even worth doing the LPC later this year, and potentially paying up to £12,500 for a qualification I may never get the full use of?
