Today, DD, (age seven and in Y2) had firemen in at her school talking about safety and fire prevention.. as they do.. and she came home all full of the info.. not at all worried but obviously remembering the talk in some detail, wanted to check out smoke alarms etc, bless! :)
Tonight, I put her to bed, then within minutes she was up saying she couldn't sleep because she was worried about fire. So we had a chat and I tried to reassure her.. but she got more and more scared and started visibly skaking a LOT and saying her tummy felt funny.. and wanted to come downstairs. So she came downstairs for a while and I made her do some calm 'in through nose, out through mouth' breaths as she actually seemed to be hyperventilating.. she was heaving too! 
Eventually got up back upstairs and I needed to do some work on the laptop in the bedroom so she wanted to get in our bed for a while. Then she said she needed to loo.. and once there (she demanded I come too) proceeded too have a very dodgy poo.. and then promptly turned round and threw up!!
She is not prone to panicking AT ALL.. is a very laid back sort of seven year old (not like my now 13 y/old who was prone to this kind of behaviour at that age and older). I thought maybe she was ill.. and that the fire related worry was just co-incidental.. but no temperature. She was still scared and shaky.. didn't want to go to bed etc. Eventually convinced to go to bed by making up her little futon bed for her (as I do on rare occasions when she's ill as high-up cabin beds not good idea re puking children) and she has been asleep for a couple of hours now.
So do you think this was a panic attack? It was as if, in her panic, she churned her guts so much that it made her sick/have diarrhoea?? I suppose we will see tomorrow, because by then will know if she is actually ill.. but that panic was most unlike her!
