It had been a while since something like this happened to me, and it happened again, in one of the worst periods possible. I had an “angst attack” of sort. I won’t call it depression or anithing similar, because I don’t find any interest in (likely wrong) self-diagnoses based just on my not-so-well known feelings.
The issue is I’m in the middle of exam season, and I need to past my last test to fully get to the thesis phase. Luckily, my supervisor is one of the best humans on the planet, so he makes his best effort to make me feel comfortable. However, I didn’t really need intrusive thoughts and a deep sense of not belonging a week before my test.
