You got great ideas so far for privacy. So you know you can do that. In spring /summer sometimes just studying under a tree can still work. But I might suggest taking a different approach. The world is a big place and for many social interaction leads to success. Not for everyone. I told my kids when going away to college that they don’t “have” to be the same person they were in high school. They can become anyone they want to. This idea I think helped them get out of their comfort zone. College is about trying and doing new things. Challenging yourself. Betting on yourself.
Unless I am totally misreading this join groups and clubs. Meet people. Put yourself out there a bit. Say hi to at least one person a day… Etc.
You can still have your alone time. I really enjoy mine. But life is too short to spend it by yourself.
