Firstly, it's really brave of you to share what you're going through. Handling school alongside personal challenges like mental health can make things incredibly tough. It sounds like you're really self-aware and that's a great first step. Remember, it’s okay to reach out for help and talk to someone about how you’re feeling, whether it’s a friend, family member, or counselor.
Regarding your revision, it might help to break things down into smaller, more manageable tasks. This can make studying seem less daunting and more doable. Setting up a simple, flexible routine could also help in bringing some structure without overwhelming you.
As for resources, practicing with topic tests and past papers can be a really effective way to prepare. Websites like Save My Exams, The Physics and Maths Tutor, and Tyrion Papers offer a lot of great material that can help you target your weak areas and get comfortable with the exam format. These resources allow you to focus on specific topics and get immediate feedback, which might make your study sessions feel more rewarding and less tedious.
Try to set small, achievable goals for each study session. Maybe today, you could solve one past paper or spend 30 minutes on a topic test. Gradually increase this as you feel more comfortable, but remember, it's okay to take breaks and go at a pace that feels right for you.
Lastly, try to do a bit of what you enjoy each day, whether it’s reading, gaming, walking, or something else that can help clear your mind and relieve stress.
Hang in there, and good luck with your revision and taking care of yourself this summer!
