It was just a short episode of 2 days.. I had to shut down my thoughts for 2 days and, now, I feel quite better.
I wonder if this is a hormonal issue. I’ve suffered from severe Premenstrual Dysphric Disorder (PMDD) since one year and a half, so the past episode might have been an hormonal issue instead of psychological one.
Anyways I’m gonna search for Professional help tomorrow.
