<human>: I've gotten to know her for about 8 weeks now, both through hanging out at university and several outings as friends. Last weekend I decided to "come clean" and tell her how I feel, which didn't go as I'd hoped.

She said that she didn't think herself to be a nice person, and had walled herself off emotionally after something (that she didn't specify) that happened last year.

We got back to normal after a few days, but I still feel attracted to her. I want to try and make things work, and more than anything I want to help her with whatever it is that is affecting her from last year. What should I do?

Can you condense the text into three sentences or less?
<bot>: Confessed to crush, she said after something from last year she "walled herself off", what should I do?
