Aup mate I was an amature boxer for 3 n half years had 4 fights and lost 1 as I felt I was unevenly matched with my last fight but hey shit happens best advise I can give you mate is just keep your nerve it's a very scary thing knowing your gunna knock lumps out of eatchother for the next 6 mins haha and don't go all out in the first round my first fight the lad come out like a bull in a china shop tried to down me straight away and faild then he was fucked so gave me a chance to pummle him lol just don't worry about your friends and family just keep focused on what you have to do inside the ring if you think about all those people watching you it will be a lot harder for you to concentrate and when your in the ring you can here everything people are saying about you so block that out aswell good luck dude
