*repost due to few answers* any advice on my situation?

Just think about it this way, you've done the hard part already, when you had you first convo with her. If i was you i'd just go up to her and say hi. Ask he if she's ok and just make general convo like, so hows your day been ok. Take deep breaths and try to relax. Just think she might be more nervous than you. Good luck
