Homesickness: I didn’t really encounter this at Scripps as I live less than half an hour away and my family kept coming up for my brother’s college admissions stuff anyways, but definitely when studying abroad. I just kept myself insanely busy and that worked for me. I would imagine it would be even easier to do so at Scripps since there’s the peer mentors and RAs constantly planning events, with evading homesickness being one of the goals.
Also, if you time it right, the traffic around Claremont is surprisingly good. For LA traffic that is (which is of course not saying much).
Socially awkward: Ah, but who isn’t socially awkward? And no, don’t change your personality! It’s pretty amazing how many different personalities we have with less than a thousand students. It’s the feminist ideas we all hold that connect us, not anything else really. So if you’re not feminist, yeah then that might be a problem. But other than that, it’s just about finding your group.
And going beyond that, my roommate my first year actually had Asperger’s, a disorder that can negatively affect social interactions, and she thrived at Scripps. So being socially awkward should not get in the way of making friends.
And if it is, you are assigned a peer mentor at the beginning of the year, and she’s someone who was picked because of her ability to work with people (it’s actually really competitive to get in). I actually still sometimes talk to my peer mentor, three years later.
And of course the RAs are there and actually will even bribe people with cookies and other treats to come to talk with them. (Especially if that RA is Vivian Zhang. Her cookies are amazing!! Seriously.)
Also, feel free to hit me up next year too if you need someone to talk with. I’m not trained for these things like the peer mentors and RAs are, but sometimes it’s nice to have someone to just rant to instead of someone who’s going to try to fix your problems 
Tomboy: Facebook doesn’t really give you a good look at the people. It’s called filters… That being said, yeah, there are plenty who fit that sort of stereotype. And plenty that don’t. Shrugs
Also, if you mean tomboy as in being geeky, there’s a primarily Scripps (technically 5C, but started by and still run by Scrippsies) called “Get Your Nerd On”. (Or GYNO for short. Yeah, you could tell a Scrippsie came up with that one lol). And…it’s awesome and has some of the friendliest people I know.
Blunt: I mean, if we’re talking Trump-style “blunt” of saying straight up racist and sexist things that really should not be said, then yeah there’s a problem. But in general, discussions aren’t always people agreeing. Professors want a healthy argument. That makes for the best discussions. The closest to an angry argument I ever saw was over a math-related discussion (a CORE class) where two women monopolized the conversation and seemed to be getting very frustrated, but as soon as class was over, hugged it out. So in short: bluntness of expressing ideas, good. Bluntness that has no purpose really other than being hurtful and insulting, never good. I’m guessing you’re probably meaning the first one, which could make for some great CORE discussions!
I actually said something once that was absolutely against the tide of ideas that came before me. But a few of the people who had been keeping quiet up to that point, then began chiming in. And no one held it against me, since I found a way of both being blunt and respectful about it.
Also, if there’s ever an idea you feel unsure if you really do want to bring up or not, email the professor ahead of time. Chances are they’ll encourage you to bring it up. Or offer to bring it up themselves if you really feel that uncomfortable.
Culture shock: I’m assuming you’re Asian based on what you said? We have a fairly large Asian American Student Program and Asian American Student Union (I’m like 95% sure those are what the acronyms AASP and AASU are short for). I believe they also assign mentors. These would be the best people to talk to.
Also, if it becomes serious enough to damage your mental health, they are working on expanding the services at Monsour Counseling. They’re a bit understaffed right now for the amount of people trying to use the services, but all 5 colleges have taken note of it and are discussing how best to deal with this, so hopefully they figure it out before you’d ever possibly need it.
Since you said you’re about an 8 hour drive, not the most feasible thing, but if you are really that concerned, you can still do an overnight at Scripps just to get a better feel of the school. There’s also the admitted students weekend of course where then you’d also get to meet some people who might be in your class (I actually distinctly remember meeting 2 people there who I’m still casual friends with), but you don’t get quite as real a feel for daily life. We don’t usually have hundreds of extra people around campus, so it’s always a hectic, very different weekend.
I might not make it to Spring Preview Days, but I do have an alumni from my school who is going there, and she’d love to host me. And to address the bluntness that I am talking about here (since
