Feeling shy around other people is normal. Usually, avoidant personality disorder means that we are conscious of others and our environment. Most of us have experienced being in a room full of people we don’t know. For example at our first day of school or a new workplace. Eventually, we warm up to others or learn to manage on our own. It is also normal to have days when we want to withdraw from social interactions entirely. Sometimes we prefer our own company, or we are simply not social butterflies like other people.
However, it becomes a problem when this avoidant behaviour becomes the default coping mechanism for every social encounter. Thereafter it starts affecting how we work, our relationships, and how we perceive others.
