I noticed that I'm always nervous whenever I'm talking to someone. Like idk how to act around them, be it my own family or friends. I was just out for a walk with my sister and I don't feel uncomfortable with her at all but for some reason, my body was very tense while talking to her. I honestly don't know how to describe the feeling but it feels like I'm under the pressure to act a certain way even though I know that I have nothing to worry about. This is not the first time. This has been going on for a long time and I act like that around my close friends too and I hate it.
I don't like this feeling. Why is this happening even with the people I'm comfortable being around? How do I act normal?
