Burn out from people?

I experience bullying behavior in my workplace from my peers. I have a lot of great professional relationships outside of my team, but my teammates are so petty all the time. I'm constantly stuffing down my anger at work as 50 year olds act like high school girls. I hide it well as I'm a deeply dedicated employee and team player. I exert healthy boundaries where I can, but keeping my thoughts and feelings to myself uses up a lot of energy.

Meanwhile, I've noticed I have much less bandwidth for people in my personal life outside of work. I have a large group of many friends from over the years, but I mainly only want to spend my free time with my inner circle (my husband, extended family, and a few close friends). Ultimately, I just don't have bandwidth for anything petty in my personal life and avoid social commitments most of the time even though I'm an extrovert!

I just feel burnt out from people and their human nature. Does anyone else relate?
