"Thank You" gift ideas!

Marina❁ • 20 yrs.
These past few weeks my boyfriend's mom has REALLY been helping me out with school and life and stuff. I had a momentary breakdown over the whole concept of "What am I doing with my life!!" And she's gone above and beyond to help me figure out what I want to go to school for and what career I would like to have etc etc
Anyways, this Sunday my boyfriends family is having a Super Bowl party and they've invited me to go, aaand I've been thinking of giving her something as a thank you gift for all of her help. I was thinking flowers and maybe some sort of gift certificate so she can get her nails done, but I feel like that's a bit basic. Can anyone give me any other ideas as to what I can give her? Thanks!
