I'm [19/M] and my GF [19/F] told me she wants a break but still loves me...

I've been with this girl for soon to be two years; and two nights ago she told me that she needs a break. She said that she still loves me and doesn't want to break up with me but that she needs a break. I know to give her the space she needs but I'm scared that I'm going to lose her. I don't know what to do from here.
