Dealing with Anxiety on the First Day of a New Job

Starting a new job today and trying to work through my anxiety. My pattern includes self sabotage that looks like panic attacks, breaking down and not leaving the house when it comes time to finally go to work. I don’t seem to have an issue applying for jobs, going to interviews, taking a class. But when it comes time for the responsibility to kick in, suddenly I’m overwhelmed. Trying to use my coping skills today and have faith that my medication is going to continue to work for me. The job is for tax preparation. I spent all last week studying and passed the exam. It’s a foot in the door while I work towards my accounting degree. Could use some encouragement and possibly advice today.
