Finding My Voice

I am currently trying to finish an important academic paper. Unfortunately, my anxiety has been causing me to avoid the task and now I am behind schedule. The problem is that every time I sit down to write I experience a very unpleasant feeling: a mixture of dread, inadequacy and fear of being judged negatively. I have the thought, “They will think I am not a good academic writer.” I’m really worried because even when I force myself to sit down and write my brain tries to avoid the task and progress is slow. Please help!
