Baltimore (CNN) -- Erika Brannock, a survivor of the Boston Marathon bombing, anxiously purses her lips. 

Her eyes jump and she is quick to smile and laugh. 

This is what someone looks like waiting to meet the person, a stranger, who she believes saved her life. 

"I told my cousin last night that it's kind of like the night before Christmas, where you're so excited, but nervous at the same time and you can't sleep," Brannock told CNN's AC360 on Wednesday.

Brannock is about to meet Amanda North, a woman who took her hand and did not let go. 

The day of the marathon, the two women were standing near the finish line when the bombs went off. 

North was there to watch her daughter run, while Brannock was supporting her mom. 

Brannock was seriously injured. She suffered bone and tissue damage, eventually requiring the amputation of her lower left leg. 

North was also injured. Like Brannock, her eardrums were busted. 

She had cuts and lacerations on her leg. But in the immediate aftermath of the blast, North was unaware of her own injuries. 

She just saw Brannock, who was clearly hurt more than she, and jumped in to help, offering her belt as a tourniquet for Brannock's leg.

"She had heard me screaming for help and she said, 'My name is Joan from California, and I'm not going to let you go.' And she stayed with me the whole time," Brannock recalled.
