Is it that she got so scared of being our of her apartment or something else?
I'm agoraphobic. It's never given me nosebleeds. Maybe if her blood pressure shot up really high, that could cause it. I'd be more inclined to attribute the nosebleed to the vomiting episode she had before leaving her apartment. That has happened to me when I had food poisoning once.
Being agoraphobic, I have to say that it's unrealistic and cruel to put that kind of pressureon someone to do something so hard (and you can't imagine how hard going to a concert would be for an agoraphobic person), for HIM. If she can't do it, she has not only failed herself, she's disappointed him. That's too much to ask. I was kind of pissed that he did that.
