I'm late.. but Preach are you still searching for ideas or have you done something already?
If your mom is the "sweet and sensitive" type... do you guys spend a lot of time together? If not.. she might enjoy somethings simple... like you attempting to cook for her (even if you can't and it's just cold cereal) and maybe renting her favorite movies and watching them while talking. Or taking her out to dinner and accompanying her on some errands. A lot of moms just miss spending quality time and talking with their kids as they get older and busy. That's if you guys don't spend a lot of time together in the first place.
In other news... I'm a libra

Apparently the only one here. lol
