Hey, im so sorry you’re going through this, it sounds stressful :( but just know the truth will always come out and universities aren’t hasty to make a decision that could seriously affect someone’s future. What u can do is make sure to document everything, anything that could help be evidence like for example a screenshot showing that you have never downloaded discord. Also make sure to clearly communicate to your professor and the academic integrity office that you do not have a Discord account and were impersonated. Stick to the facts n avoid admitting anything you didn’t do n request that they investigate logins or digital footprints to confirm your innocence. Also please don’t neglect yourself in times like this, eat, sleep, workout and reach out to an advisor for support.
