I think this scene with her outbursts were... maybe a bit too much. I mean, yes, there are a lot of hormones flowing through your body making you changing and some times a lot of unpleasant things happens to our body, but from one night to the morning Riley immediately starts acting completely differently. Or did I get it wrong?
I see Riley's mom is smiling when she responds. So it means that she doesn't really understands what Riley is going through. (maybe mom forgot her teenage years)
1:30-1:40 I noticed that fear and disgust in this scene act really similar to anxiety, because disgust wants to be friends with the probably popular girls and fear wrote a whole list of possible things that can go wrong.
