If you want to make intimate friends, you must first open your heart to others. In primary school, because everyone's thoughts are simple and there are no distractions, the friendship between friends is very simple. But in junior high school, everyone gradually began to have their own understanding of their own thoughts, psychology and body, so everyone has their own privacy, and it is increasingly difficult to make intimate friends from now on, but that doesn't mean that they can't make intimate friends. The key is you. The mind in high school or college is not so terrible, it is a kind of training for your life. You should grow through training, so that you can adapt to this society. Come on, I'm sure you can make the bosom friends you want in the near future.
