I have a big problem and I hope that someone can help me.

Tomorrow I'm going to take the first part of the English exam. It is "speaking" part of the exman. I'm pancking and I feel nervous. Moreover I think that I will not pass the "speaking" part of the exman because I do not know all words and topics. By the way, I really do not know what I'm doing to talk about. It is a terrible feeling. I almost going to cry. I do not know what to do. Can you help me? Maybe somebody can talk with me on Skype. I really have no ideas.
Anyway, thank you for attention.
