PLZ HELP! What do you think would be consequences of not having a fight-or-flight response?

The fight-or-flight response plays a critical role we deal with anger, stress, or danger. It prepares our body to fight or flee from the threat. Without it, the body cannot help you protect yourself in a dangerous situation. We lose much needed energy and strength. We cannot really defend ourselves!

for me i have felt invisible when i was clearly struggling,or,i made a great achievement ,and,nobody took to notice me either because they just didn't see it,or,people just turned their back on me.i can see a person being invisible by choice,or,without choice like i did.the people who are invisible by choice don't try to talk to people,don't try to make friends,and,keep to themselves.i haven't been one of those people so i couldn't give you a reason.

hope this and can i get bainliest my dude : d
