Hi everyone! I suffer a lot from anxiety but in general I keep it at bay with my routine and stuff.  
Lately I've been really challenged by my Girlfriend. We moved in together in October and since then it's all fine apart from the fact that I started to notice that she is prone to what I think are panick attacks.  
She's a little too harsh with herself and has low self esteem, so when it comes to discuss important matter or when she's under exam she experience what she calls "blank page" problem: she feel insecure about everything and overwhelmed by the anxiety and start to cry while staying completely in silence and "calm" on the outside. She says that cannot think of anything while in that conditions and its mind is like a blank page.  
The fact is that this prevent her to take part into discussion and to do well in University exams (she's a year and half behind).  
Do any of you know any breathing exercise or practice that she could adopt to alleviate and regain focus while this condition kicks in?  


Thanks in advance for your help and attention
