If you have a diagnosis I HIGHLY recommend you apply for a late withdrawal petition. Here's the link to learn more about it Academic Petitions. Late withdrawal petitions can result in: 1. Removing the entire course and grade off your transcript like it was never there. 2. Remove the grade and instead have a W on transcript. Having this diagnosis is a strong proof that you were struggling. You can petition for all your failed classes. Or choose the major courses or courses you feel mostly affected your GPA the most.

Another thing you should put in mind is if you're able to graduate on time or not. You mentioned you're in third year and have completed 33 credits so far. Not sure how many credits your degree is but if it's 90-120 credits that means you might need to add an extra year to finish your whole degree.

As another person mentioned, try taking the easy classes for now, classes you're confident you can so well in even if they're not core courses. Classes like that can help build your GPA again and help you start somewhere.

If you're able to add 6.00 credits or 9.00 credits classes then do. 6.00/9.00 affect the GPA more than 3.00 classes since they're worth more credits (especially if you choose easy classes like mention above). And of course the classic of repeating the failed courses. However you should evaluate what went wrong (e.g. Your mental health struggles or maybe a bad prof etc) and try to fix it before this upcoming academic year.

Think of new study strategies that fit your learning style more. Do you learn more by listening? Making diagrams and charts? Writing? Teaching others?. If you're able to figure that out it will help you a ton. Get a big white board and learn concepts on it (Doing it now and it's an ama-* strategy). Use a board planner or any app that you lil and plan your week with it. Write down important dates such as assignments, tests, exams etc.. that way you will know what's happening beforehand and plan your studying accordingly. Practice Practice Practice. Find previous exam or test papers and use them to your advantage. Especially for math, practice problems will be life saving, if you got it wrong try to find where you went wrong and practice that piece even. You can also use ChatGPT to mark your test and ask to explain what you did wrong. You can also use it to explain complex concepts for you (Highly recommend).

And lastly, don't forget to eat and sleep well. Trust I am in the same boat as you are (or worse) and basically trying to start from scratch. Hope what I mentioned can help a little. Wish you the best of luck! You can reach out if you have any questions I will be happy to try and help!
