You need to rest for real it sounds like you’re on a path to a burn out, if u stress more. Getting your desired results is not the end of the world believe me. There’s foundation years or directional courses that you can pass in order to get into ur desired course. For real it’s going to be okay, but I’m sure you’ll get the results you want either way im sure you put in all your effort believe me 10 years down the one you’re gonna look back and think how silly it was to stress. You’re good I promise.
