If they're mature, they should have some kind of sympathy and sense it, since you brought it up and explained to them, so they should be chill and make you comfortable :) instead of ankward silence...... if not, just leave the club, it's human filter. Also you can try just give 'em time, i remember that back in the school, i literally shocked dancing club with my speech, because i was coward stutter back in the time and they had absolutely no idea about it, but you brought it up from the start :) hands down
