Sit down where you generally study and open a book. Promise yourself you will at least page through the relevant material for at least fifteen minutes. Before getting up, spend ten minutes writing out what you remember. After an hour or two do it again.

Breakdown what you need to do into manageable segments. You already know you can do the work. The majority of tests confirm what you know.

Berating yourself is unhelpful. Would it be helpful to talk to your teacher to see if you are entitled to an accommodation? Perhaps the teacher might know someone who would be agreeable to tutoring you. The idea is to think of ways to accomplish your goals rather than to focus on the negative stuff that is so devastating.
