I do this with my mom sometimes. I remember if she would complain about a coworker, then I automatically hated that coworker. And if I ever met that person...let's just say I'm not good with hiding my feelings and so that person automatically gets the cold shoulder from me. When my mom would be stressed over something, I take on her stress about whatever it is. We were too codependent. I had to separate myself from her and keep some distance between us. My life is fine, I can't be stressed with her anymore.
