Join the club...not the first and not the last. Wait til you go and feel responsible for your dive buddy especially if it is a loved one... Folks gave you sound advices here and I will just add my .02 pennies here....we get apprehensive if we are about to do things we hate doing because of our limited skill sets in certain areas and fear we might fail miserably, we fear certain things or creatures because we despised them, (snakes, rats, etc), they inflict pain or represent danger to ourself, things we have no control over (fear of height) or simply because they are unknown to us and/or not having those before (flying, skydiving,etc).
My advices...keep your mind busy about things you have control over. Equipment is a good start. You could produce a checklist and go through it to ensure you have all the equipment that you will be requiring and pack in a logical sense.
2) The unknown...attempt to obtain maximum information about that dive. If there is a schematic of the site, obtain a copy and go through it by yourself then go through it with your buddy well before the dive. A good excuse as any to meet for a pint. Memorize the details or plasticise them. What type of a dive is it going to be...everybody off then follow the lead or pairs diving on their own. If it is the latter...start planning your dive in a logical and easy to remember sequence based on your qualifications, your equipment, you and buddy gas usage, you and buddy comfy level and what you would like to see or accomplish.
As for the dive...first time on site...follow the KISS principle. Keep It Simple Stupid. Remember, you control that dive and not the other way around. If starting at a mooring line start your exploration by diving straight line following recognizable features, take a bearing, venture a comfortable distance, come back to mooring line, do same in other directions, etc. If it is a wreck...do same, simple plan and follow it. Do not attempt to cover the entire site all at once.
As for the fear of ruining the dive of others...I have also seen less experienced divers do just the opposite...save the dive of most experienced divers who forgot to bring enough weight, a mask, a save a dive kit (orings, straps, etc), find a lost or dropped item...It is a big community and we are only humans after all.
Oh, I forgot...have fun because that's why we do this...to meet people, visit new places and have fun. I would not say the same about going to the.........dentist.
