When my parents dropped me off at uni I screamed at them they were abandoning me and chased their car out of the car park banging on the windows. The next few weeks were terrifying, somehow I got through that and my parents wouldn't let me come home, they said if I came home they'd just drive me back there again.

Once I settled in I had 3 of the best years of my life.

That said the drop out rate at unis in the first few weeks is very high from people who just don't like it.

I'd say find the uni's health office, see if you can sign on to talk to someone about receiving support for an existing mental health issue and try to stick it out for at least two weeks. After that if you still hate it then think again. But what is two weeks out of your life?

It's a massive change and you need an adjustment period.

I bonded with my flat mates over a few dozen cans of beer, but I've the feeling you're in America so the age is 21?

I also made sure I came home as often as I could to visit and see my family. When times were hard I just reminded myself it wasn't long until I was visiting home again.
