I know that feeling a bit too well, myself. My brain knows I am going to be OK, but it's not always so obvious on a day to day basis. Just keep your focus on a really small time window, Poschan. The next hour, the next day... something manageable. Friday is coming very soon. It will be difficult, but then you will be able to adjust your focus to the next interim goal with that huge hurdle behind you.
