Faye is right, college is COMPLETELY different. I hated school with a passion. I don't mind college, I can go to my classes then go home.
Also, you have NO GROUNDS whatsoever to be telling us about "we CLEARLY must not have been treated the same way" as you. It's flat out insulting. Many, many of us have been treated like crap, abused verbally and mentally and some physically, and have found ways of dealing with it. For many of us it was horses. Life is what YOU make it. If YOU are letting all of this get to you, that's on you. Professional help would help immensely if it's getting you down this badly. School is full of nasty people, and it's up to you whether to let that get to you and shut down, to ignore it, or to reach out for help. But shooting the rest of us down because you hate school and we "must not understand" you and what you went through is juvenile and insulting.
