Why do I feel like this 😩

First time ever posting, I'm 4 DPO today and I feel extremely sad, annoyed, angry and irritated for no reason, nothing happen.

Never felt this way, not even as PMS symptom.

Do you guys ever experience this before? How did you deal? Even as I'm typing I'm angry, I went shopping about 20min ago and I was about to cry (had to stop myself because there's no reason).

Will try watch some comedy, hopefully that will cheer me up.
