Starting school support

My boy starts school in less than 2 weeks... aghhh!. I thought I was handling it okay - until I started talking to some close friends tonight. I realised how nervous and stressed I really am. I have already spoken to many of you who also have allergic children starting school this year. I am thinking it might be helpful to start some kind of support group so we can help each other get through the next few weeks.
So, not sure how to go about this - any advice would be welcome
