I think you know deep down that moving isn't best for you. You clearly stated very logical reasons why a move isn't the best choice at this time. Maybe one day, but not now.

If your job is really draining you, focus on making a change. Work on finding a more suitable position. Meanwhile, can you see a therapist to help you cope with your current job and the job search?

Try not to be hard on yourself. Your head is in the right place. Anxiety is the pits. *hugs*
