parents falling out at the school gates!!! help!!?

[Nikki H]

my son is now in reception but he was in the same nursey school last year. Myself and a few others had made friends and spend weekends and school holidays together doing various activities. We all took part in bitching about each other a little and now all has gone wrong.
One of the mums said she couldnt sleep at night and so i went to her house and said maybe we have all said a bit too much and now its impacting on our lives, she thanked me and we moved on for that day anyways
the others didnt seem pleased that i did this and the 3 of them have now started ganging up with evil looks, deleting me off facebook, ignoring me ect.
Im aware this sounds pathetic, and i wish i hadnt been involved. but it has happened, so i am here now panacking about the school run, dropping off and picking up...... i feel really anxious and am considering moving my son to another school....but then i think why should he go through with this. what should i do? has anyone else had a similar situation?
ive tried talking but that got me to be public enemy number 1.....any advice would be great!!
