I am an INFJ myself, so I know how it feels. It's hard, especially when the people you really love don't really understand you. It's normal to feel alone for us. It's like your emotionally invisible. People see you physically, but they can't really ever see you emotionally. Crying in front of others, I absolutely hate it. If I cry in front of you, you better feel special because I don't let people see me cry. It's ok to feel like this sometimes. It's good to have a certain amount of alone time though. Sometimes being alone for too long can have a huge affect on daily routines and personal relationships. If you ever need to talk, please don't hesitate to read and comment. You can also private message me. Even if you aren't an INFJ, I am always here to support, give advice, and listen to your every need.
