I agree with TinyRabbit, you've not failed at all. Cripes, anyone's grades would take a hit after their Mum attempted suicide. Add ill health and it's bloody impressive you're still managing to do all that you are doing. Bravo to you!

Try not to be too hard on yourself. Keep plugging away and I'm sure you'll get to where you want to be. If you don't manage to get to U of M, don't be hard on yourself, sometimes these diversions that life throws us can be better than what we hoped to do.
