I have an interview in 5 days and I just cannot study

I don't know what it is. For starters, I was supposed to be having 2 interviews because another person reached out to me too, but his responses weren't prompt enough, and I fell sick a few days after responding to him for the first time and asked for the following week instead of the same one. Then, when he gave me a new time it happened to fall exactly before this other interview and I found that risky, so I explained there was a scheduling conflict and if we could do the next day. Radio silence since then and I really wanted that opportunity. Now the anxiety and dread are killing me.

Besides that, I feel dead/burned out inside. I just cannot study and haven't been able to in weeks. I think it's some combination of burn out and now PMS ? I don't know. At least my psych doesn't believe I have ADHD so clearly that cannot be causing it. I finally woke up at close to 9 and somehow impulsively ate, then doomscrolled and now I am blankly staring at my computer.
