My Yarn Broke

Help!! I was trying to knit fingerless gloves on dbl pointed needles and i really messed up. The joins between the dbl pointed needles was loose. While I was trying to tighten the join I pulled the yarn WAY too tight and the yarn broke off!! YIKES!!!!! The yarn attached to the needle is only about a half an inch long & I'm already 5 inches into the pattern.

Please do I reconnect the stub to the skein of yarn it separated from? Is it even possible?

Thank you in advance.
