Is a joke. You start with high hopes for a change from middle school and excitement in your freshmen year, but no. It's gonna be the same. Oh, and it gets worse as you progress into senior year.
You go around looking for
friendships, failing to realize
you're not gonna see them again after four years. You stress over rigorous curriculum such as AP classes, get yourself involved in school activities... all just to impress colleges (so
you're not really passionate about
what you're doing). It's less likely you'd take
academics seriously in high school since you're overridden by the perpetual stress and negativity around and at you. And you run into these so called "friends" trying to be BFFs with you without foreseeing one day they'd get tired of you and move on, leaving a hole in your heart that never heals up if you've develop feelings for them. At that point, you're gonna think about turning everyone away from you or limit your socialization thinking it'll avoid that problem when it'll only make you feel worse that you're alone.
Mistakes are NOT okay in high school. If someone (teachers/classmate) hates you from the beginning, they're gonna hate you until the end.
Oh, and don't think about revisiting your old high school either. It's a waste of gas, money, and time to get rudely chewed up by the staff kicking the alumni out.
