agree with the some of the above sentiments but I think some of the posters above did not see that the OP is finishing the AOW class, not just going diving, so the deep dive is mandatory
Slowly slowly is the key to rebuild your confidence. I don't know the dive op but explain the situation to them, hopefully they are understanding enough to cater to your anxiety. Speak to your group, make sure all your buddies understand.
Start off with a nice shallow check dive. Make sure your weighting is correct and you are comfortable getting back into the equipment, at a dive site with easy access, small currents, free of hazards that might startle you - excess boat traffic, overhead environments, great white sharks, that sort of thing. (Just kidding about the sharks!)
For the AOW deep dive, you don't have to hit 100ft, the requirement is 60 - 100ft. Get the others completed first and save the deep dive until last if possible - maybe the first dive of a third or fourth day, if your dive shop will accommodate you, or get a few days diving in before you start the class.
regarding the night dive - you do NOT have to do a night dive, at least not for the PADI AOW class. Only Deep and Navigation are required, unless there's some extra law in your area. Again, if you want to try, save it for later. If it is possible, find a nice shallow, easy to navigate dive site with lots of shore lights - they are amazingly reassuring - and one that you have dived during the day so you have some familiarity with it.
Hope that helps and good luck!
