How to handle feeling out of place at work
Try to label what you're feeling.
Ask yourself what is keeping you from belonging. Co-workers sometimes hang out with their own age group by default and maybe you're much older or younger.
Perhaps you are a manager and feel excluded from your subordinates? Maybe everyone else has energy for the job, but you're dealing with. There even may be varying levels of lifestyles, values, or interests separating you and your colleagues.
