You're right, reading ch.1 again, his livestream is a Consultation Corner, provided by the TL note. His trauma definitely came from the text he received after his livestream.
I think it's heavier than just a former consultant that had a pretty bad advice then cursing him out on him, if it is that, maybe the advice MC gave had so much a drawback that it wrecked the consultant's relationship or life at home.
