Everyday is an opportunity to try again. get some rest for a few months or a year and get into it again. You can only stop trying when you breathe your last. Don't quit if you really want it, just go get!! Meanwhile find some legal positions like tribunal assistant, investigation assistant, etc or apply at the bank. Get into some good job with your 2:1 you might even like the non-legal posts. The only think NOT TO DO is sit home and cry. Cry once, dry the tears and grab opportunities worth your 2:1.
