Like you, I sum up myself like this: I feel like living in a glass bottle. Everyone can see me and chat with me, but no matter how close we are, we are always separated by a layer of glass ... I am afraid I will be disappointed, so I dare not take that step. Later, I may grow up, and some things can't be solved by myself and I can't figure it out. I began to try to trust them, listen to them, and get along with others with my heart (which is certainly worthwhile). Each of us has only two hands, so God created friends. Friends are really important. I think you can try to convince your heart to accept friends first, and then actively encourage yourself to get in touch with people and find friends who can make deep friends. Don't be shy, tell your feelings about your friend frankly (what qualities do you like about her/him, don't be stingy with sincere praise).

To sum up: communicate frankly and treat each other sincerely. Feelings are mutual. I hope you can find friends who talk about everything as soon as possible.
