Iffy on stage performance

Date: 12/4/2018

I am in a weird high-school or college production of wicked mashed up with the wizard of oz and swan lake. It is opening night. I play the black swan/wicked witch(more witch than swan this time) and am always fiddling with some kind of DIY costume contraption before my cue to go on stage. I go out and deliver a few lines then Ad lib a few more, completely forgetting the rest of my cues and real lines. The rest of the cast covers for me and I pick back up at my last line then exit the stage with my tail between my legs. Everyone seems to think I did just fine but I really beat myself up about it.
