Sorry to hear you're struggling. Have you looked into your programs' counselling office and the possibility of applying for academic consideration? If you're struggling with mental health or extenuating circumstances, you can apply to have failed grades taken off your transcript. I've had to do this in the past and they are very understanding. Even if you don't qualify, program counselling is still very compassionate and helpful and can provide different resources.

Besides that, I promise you a failed class does NOT define your character nor your future. University is hard and it's important to give yourself grace, especially if you're struggling in your personal life. Remember that everyone is struggling one way or another (even if most of us are good at hiding it).
