A few years by now - sort of over all the hard stuff. I’m pretty sure you’ll be fine for the presentation. My personal opinion is that the harder the pre-performance stuff hits, the better the actual performance. Which sounds kinda weird but this is what I’ve observed. Would also recommend not ignoring the post performance stuff. Like having a mental list of things to do immediately after you’ve finished - from packing up the equipment to organising notes etc. This really helps conquer the jitters.
