It’s not really appropriate to call co-workers mom, and nurse. They are NOT your mom or your nurse. Of course it’s going to be a lot of hard work to become more emotionally mature. But what it your alternative? Same thing different day.

Your comment about “I’m just a little kid” was a bit odd. You are not a little kid. You are a full grown woman. Anyone can have a bad day, but having a full blown melt down over spilling a cup of coffee might get some strange looks. Of course that would be embarrassing. However, These are co-workers, not friends or family, and are not obligated to understand you psychiatric situation.

Are you addressing these issues in therapy? Maybe if once a week isn’t helping you could try going more often?
