I know exactly what you all are referring to. I'm also a nurse at the hospital, although feeling excluded at work doesnt bother me anymore as I tend to brush it off pretty easy. My mentality is I'm there to work, the priority isnt to make friends cuz I have friends outside of work environment.
But often, I feel isolated and invisible at home. My partner is supportive, but being an alpha male, he seems oblivious to this. (Its possible its just in my head). There are certain people in the household that are so good at making me feel inadequate and insignificant. Sometimes I rub my belly to comfort myself, saying 'its me and you bub'...
Needless to say, Im still feeling uneasy being here.
