I'm not able to show emotions in public?

I dont think its necissarily a bad thing to not show your emotions in public. Your emotions are you emotions, who cares what anyone else thinks. And as far as not crying in public- I NEVER cry in public. To me crying is such a personal thing, why would I want to share that with a bunch of strangers! (not to mention that no one looks cute with a red smoosh face full of tears and snot bubbles) I think your friend needs to chill out a little...she seems a little too worried about what you do. Trust me as much as you think people are staring at you- they're not...they're too worried that your staring at them. I wouldnt put too much more thought into it.
