As long as you realise and accept what you are feeling is normal and try not to let it consume you and drain your energy, you should not have a problem. The nervous feeling will not be as intense as you gain experience, but you will always feel nervy before a fight. You just need to accept it and keep a positive state of mind towards the coming bout.

This is a common problem. There is lots of energy inside you, all you have to do is figure out how to access it. You can train yourself to reach inside and bring it out. You need to do many more intense training drills. Once you drive yourself to the point of exhaustion then learn how to give a bit more, you will find that the pre-fight fatigue due to nervousness will go away.
