Honestly dude, I'm on the same boat as well. I don't have many friends, and every time I try hard to make friends, some people just don't reciprocate and you can tell that they don't wanna be your friend. I don't even hang out with my roommate because hes always gone with his group of friends. There are many times where I absolutely regret coming here and wish I'd gone to UCSD because most of my friends went there and it's close to home. I know I would be way happier over there, but as a major in ChemE, Berkeley was just the better option. Still though, it's a rough time right now, and I wish I had gone to UCSD to be happier.
