Wait! when i was reading, i felt like you were speaking on my behalf. I am facing and feeling exactly what you have mentioned. I got an ATAR of 89 in my year 12 and my brother forced me to go to top uni because of my grade but i wanted to go to average uni due to my stuttering and social anxiety. I have enrolled myself for BSc degree and i will be starting soon. i am very very scared, i am facing the same situation as yours. don't know how will i handle the overwhelming life of University. May god help us
