Coping with stress and anxiety

I’m a college student and a year ago I was doing really poorly with regards to my mental health and I failed a professional cooking class that I was not emotionally or physically capable ready for due to my mental state at the time.

While I’m looking more into my health so I can have more energy and hopefully becoming happier I have to retake this class this semester as it is a requirement for my major. My first class starts tomorrow and I’m already having a sense of anxiousness and dread about it. I can get really worried about classes to the point where I can’t sleep because of it and I can starting to feel it happen already.

I’m usually a really studious student but I know I’m not a passionate or amazing cook and have not interest in pursuing it professionally(I just want to pass this class). I froze up a lot last year because of my anxiety and always felt rushed and like a failure to the rest of my cooking partners as a result.

Does anyone have any positive tips for dealing with anxiety when facing difficulties so I don’t avoid this class and can hopefully overcome and not fail this class again?
