Graduate College before my Great Grandmother dies

I consider that my Great Grandmother is the person who raised me. She is now 94 and also resides in the Phillippines. I’ve been in college for awhile and the only thing that inspires me to continue to go to school is because of her. The challenge is that I don’t know what to major in and so this process will take a while to have this goal done. I can’t give her anything but a few calls to her here and there but I don’t think there’s a better gift than to show Nanay that I have done something with my life. She has always talked about my education and the importance of it. If she does passes before I get this goal done I would feel like I have failed. It’s better to do it when she is still alive.
