I was depressed at university. The courses weren't interesting, my neighbours were verbally abusive, and my long distance relationship was ending badly. I ended up going to the university psychiatrist and just cried my eyes out. I didn't pass with the grades I wanted but I got through it. If I'd do it again I'd just talk to people. Not everyone will understand but if you're lucky someone will. Other than that all I can say is "this too will pass"
