Hey @Rayven, welcome to the forum.
I would definitely say I'm a fawn. I always just tried to please people and avoided conflict... by avoiding people in the first place mainly. I've always had issues saying 'no' to people and always put their needs above my own. I only discovered all of this recently myself and have been looking into it as I've found it explains so much about my behaviours and explains why I do it.
Yours does seem to not fit any of the standards. I know there is the flop response where people sort of just surrender or collapse in a stressful situation. I think people who have this reaction just basically 'play dead', unable to fight, flee, or even freeze. Their feelings of helplessness and/or hopelessness combine with a sense of resignation of a threat. So if you're on your own and dont feel like there's anyone there to protect, then i'd say you're closest to this flop response. But people can display traits of different responses in different situations. so for you, this probably happens when it involves other people. But on your own, you seem to display traits of the rarer flop response. As you pointed out, yours isnt a fawn response where you would try to make people happy to avoid harm, instead you 'submit' allowing the situation to unfold and intentionally exposing yourself to the danger.
Do you think your past has taught you to face trauma by just bracing yourself for a inevitable and predictable outcome? Therefore seeing no point in fighting or fleeing because you feel it wont change the outcome. I'm curious about what you think.
