You really should. And for being dumb and a coward... Well, it's alright to be afraid, especially in your position. Just tell them, then you won't be afraid, you'll just have to deal with the aftermath.
Well, I planned on telling them this year. But, time is moving so fast. Like, how did January just end? Oml
Then, I think that I can't tell them this year as well cz I have a board exam coming up in Feb 2026. The medical leave will cz my grades to drop.
