They all made fun of me

Today there was a meeting at work. I joined virtually but kept myself muted and off camera. I don't know what happen but they all made fun of me like I couldn't hear them. HR is only me and 1 other person also in the meeting. CEO obvi was at the meeting. I am looking for another job. I see my therapist on Tuesday. I just don't know what to do. This is an everyday thing almost now. I am on anti-depressents bc of this job
