It turns out my last notification was a false alarm. I thought I had been feeling better, but my waves of sickness come back unpredictably. Therefore, I'm taking an official sick leave until April 14th to avoid having to cancel classes at the last minute.
I will send another update near April 14th to inform everyone whether I will be ready to work again by then. I'm so sorry for this inconsistency.
I miss you all and I hope for a speedy recovery so that I can get back to the grind. In the meanwhile, happy learning, everyone!
