It's completely normal to feel this way, as many people find comfort and enjoyment in the social interactions they have with their colleagues at the office. Building relationships with coworkers can help create a sense of community and support, making work more enjoyable. Feeling lonely or disconnected during holidays or time off is also common, especially if you have limited social interactions outside of work. It's important to prioritize building relationships outside of the office as well, to have a well-rounded social network. Remember, it's okay to enjoy spending time with your colleagues and find happiness in those interactions.
