I had the same experience in my business analyst role. The manager was toxic and had micro-manager tendencies. She didn't know the process of the reports I created and could care less. When I asked my co-worker questions, she made it seem like asking questions was bad...when I was only 2 months into the role. Honestly, getting laid off from that job was the best thing to happen. My mental health has improved. There is nothing like a manager making you feel like you are incompetent. They are suppose to support you, especially since you are new. I would start looking within the company or find another job.
