verona:Is this PADI AOW? If so, I think the max. depth on AOW deep is meant to be 100ft so I don't think your instructor should be taking you to 120. It is only if you do Deep Spec that you should be going below 100. Ask your instructor about this.
As to your nerves, that's perfectly natural.
AOW Deep Dive is 18-30m (60-120ft) so 105ft is fine.
