So... I think she's asexual after all
That's a huge leap. That's like saying a woman is a lesbian because she's having a hard time being with men after one bad (ie rape, molestation) experience.
Honestly, we don't know what she really is at this point, because she doesn't know. She's depressed, full of anxiety, and has little to no experience. She has trouble leaving her house let alone having sex with someone. This one experience does not an asexual make.
As someone has already said, she needs therapy so she can figure herself out and decide what she wants from life.
