Is it normal? suddenly repulsed by meat?

I already rarely ate red meat but then when I was confronted by it because my friend made a beef meal normally I'd eat it but this time I couldn't I felt sick to my stomach looking at it. When I tried to put it in my mouth I gagged yuck.

So that was about a month and a half ago. Now I cut out red meat entirely and don't eat beef or pork.

But I was okay with chicken as it's always been my favorite food. But now I started feeling no desire to eat chicken, in fact I now am a vegetarian out of nowhere rhis happened I didn't watch any animal slaughter videos or anything this came out of nowhere.

Is it normal? Wth..
