Selena Gomez's best friend, Francia Raisa, didn't know if she'd survive donating a kidney to her BFF ... which really hit home when she had to write a will.

Francia and Selena told "Today" the donation process had to be sped up because Selena was in such dire straits she couldn't even open a water bottle. What normally takes months was done in days.
Selena also thanked Francia for volunteering her kidney without being asked ... once she found out she was a blood match, which is extremely rare.
