Since you’ve already done it before, it will be just as easy if not easier doing it again. Breathing is key. If you’ve ever done yoga, look at it as a yoga exercise. Just take your time performing each task. It isn’t a race. You don’t have to beat the clock. I’ve never found depth an issue. In water 30’ is the same as 5’ in terms of performing tasks like clearing my mask and/or recovering my regulator. You’ll do great.
