Martial Arts Suggestions

Alright so I recently decided I want to start learning some sort of MA to both get in shape and learn how to protect myself. I used to do Taekwando until I was 11 (got a red belt!), but I am now open to other MAs as well.
20 years old, female. looking for something practical that I can use if I have to...

What should I go for?

Thanks!
