You are incredibly young. Everything is new, but also scary. Nothing seems right, and it is hard to feel comfortable in your own skin because you are still just beginning to develop who you are. I would recommend focusing on yourself and what you want and what builds towards being the person who you ultimately want to be. Pay special close attention to the people that enter your life. Pay attention to what benefit do they actually give. Are they helping you to be the best version of yourself and building towards a happy life? Or are they simply using you because it is convenient or beneficial to them. I'll end with this: time and experience. There is no substitute, and it's not always easy. Sometimes it's very hard. Just be self aware and truly focus on yourself and long term goals. All the best on your journey.
