pinkkoala- Dd1 gets a D&V once a year (roughly the same time every year so i get extra anxious around that time), dd2 is 4 and has only had D&V once but vomits if she gets a high temp. We all had a bug a month ago, i was the first to get it (so out of the blue), followed by dd1 (4 hours after) and then dd2 (a few days after). I had to call my mum to sit with me as i was shaking and crying, i called out of hour GP who gave me anti sickness drugs (dh had to collect them and by the time he got back i had been sick) so now i keep anti sickness drugs in the house.
Go to your GP tomorrow and explain your situation, get some anti sickness drugs to keep in the house.
Dd1's school always has D&v going around but dd1 rarely gets it, i always get very anxious when i hear one of her friends has it or when dd comes home and say's 'so and so was sick today', i panic like you are now, i get anxious i stop eating and i can't sleep, i lie awake listing out for dd1 in case she's ill, i panic if they don't eat their dinner or look sleepy/pale. I know how horrid it is living with this phobia. I'm counting down the days to the summer holidays when they wont be mixing with bugs at school.
Take your self off to your GP, ask to see a female GP or nurse (they are more understanding), ask for the drugs and ask if you can go on the waiting list for CBT.
I started CBT 6 weeks ago after trying hypnotherapy, i decided to go private as i felt i needed to sort myself out as soon as possible as its taking over my life. I am starting to feel more relaxed but i still keep up with good hygiene.
Detol is fine to put in a bath (my mum used to put it in my bath to stop my itchy skin getting infected), the dd's don't need to know its in there. I use it after we have been to soft play or birthday parties.
Children will always get D&V bugs however careful you are, its important that they get bugs to build up their immune system, the bugs will lessen as they get older (i hope).
Last month was the first time i have had it for 4 years. People with this phobia tend to get less bugs or just get the D part, by taking the anti V drugs the D could be worse (but i can cope with that).
You could try taking a herbal medicine for the Anxiety like 'Calms', i find they take the edge off.
Sorry for rabbiting on .
