Anxiety and creativity

I’m really struggling with anxiety in my job. Whenever I think about work or whenever I am working, my body feels tight and my chest feels heavy. I’m thinking that I don’t know what I’m doing in this role. I’m thinking tons of self-doubt thoughts, questioning myself. I was hired to change our QA processes and while I have some ideas, I’m struggling to feel like they’re even worth anything and I think I need to come up with better ideas. Then I feel anxious and it blocks me from being able to think creatively and come up with solutions.

I don’t want to feel this way anymore.
