When you're feeling lonely in your work role, take a moment to pause, raise your head, and consider what you might need to do to connect with others. I believe that loneliness in the workplace is a choice; a choice between connecting with others or not (withdrawing). I love helping people see connections in the workplace.
I've felt alone at various points in my work life, but in virtually every case, I was able to wake up and connect with others. Any kind of isolation feeling has been caused by my withdrawing or by changes in my personality that pushed people away. At a few points in my life, I had produced some toxicity that others didn't want to be around at work, and I needed to address it. Honest friends, a coach, and mentors were essential in assisting me in seeing this in myself and guiding me back.
Ever get a promotion, did everyone around you change? We frequently assume that people are jealous of our advancement, and we alter our relationships as a result. We, more often than not, are the ones who make changes. We change how we speak with them, how we interact with them, and how much time we spend with them. We are the ones that choose to make assumptions and act in a way that may cause a rift that should not exist.
Change and progression are sometimes essential when you are evolving in your career. It's then up to you to let go, move forward, and form new relationships in this case. Letting go without new relationships creates this feeling of being caught in the middle of a growth transition, and more loneliness can set in. Recognize this quickly and forge new relationships that support your growth.
The struggle with isolation is real in the workplace. You have the choice to help yourself. Find comfort in knowing there are always friends, mentors, counselors, and coaches willing to help. But the choice is still yours. You must ask for help and be open to their feedback.
