My A level is coming real soon. I have studied non-stop for 4 days and today I feel my brain is overloaded. I'm tired. I'm stressed. I wanna rest. I don't know what to do... I want to have good grades in order to fulfill my dream in becoming a dentist! God please bless me. I feel like giving up... I feel like crying... HELP!!! I still have a lot of things to study... =(
