I'm sorry that you are going through this. I can see why some of this stems from your past job experience. It is triggering when you have problems with the next job. So remember that this job is different and focus on the fact that you were told that your job is not in jeopardy. Also, no one is perfect, and everyone makes mistakes on the job. I wish your therapist was more helpful. It was insensitive for her to say that and to make that assumption. I relate to the fact that my past job experience was terrible, and it has affected me when I made mistakes on the next job. I get extremely anxious when I make mistakes, but I just try to remind myself that it doesn't mean worst-case-scenario is going to happen (and it hasn't yet). So try to catch yourself when you are thinking the worst and remind yourself that nobody told you that your job is at risk. Please hang in there!
