If you are serious Is there anyone you can talk to at home that can help? A parent, relative, teacher, sibling or doctor? It is good to have some one around locally that you can trust and talk over your problems with.
I am not sure that posting that sort of post on this thread will really help you. People are finding it hard to know how serious you are due to your previous posts last week. Remember Ms Sally's "crying wolf" story?
As for the egg and the bator temperature, you totally know how to fix it. If the egg is dead it is dead and no amount of panic will help it.
Fingers crossed that it is still ok.
