I was opening up being vulnerable about my childhood growing

I was opening up being vulnerable about my childhood growing up, not having many friends, at my outpatient rehab class with other fellow patients and the counselor. Long story short, I was mocked and what I said was thrown back in my face. I felt extremely embarrassed, and held back my emotions. Counselor ignored the comments. Waiting at the bus stop thinking about the situation I started feeling angry at the guy mocking me at the counselor for not saying anything, at other patients for not stepping in, but mostly myself for not defending myself. Then I felt at peace, cause I realized the guy mocking doesn’t understand how to process his emotions and wanted to make light of what I was saying to make himself feel better. Lesson learned for me cause if he says anything again I will set boundaries and defend myself. Goodnight
