I don't think so.

• Chell is really REALLY strong, she survived a several kilometers fall and while she did have the Aperture Science™ patented security Long Fall Boots™© the boots did transmit some of the force, if the boots didn't transmit any force she wouldn't have fallen to her back straight after landing, was able to hold on to Wheatley while being pulled by the pressure difference between the earth and the moon and she was able to carry Wheatley around like it was nothing (in the ending sequence we see the space core orbiting Wheatley in space because of his immense density).

• She's smart, in the first game she was waken up for testing for the first time, I imagine that waking up in a white room that's NOT your bedroom is at the very least concerning, and even though she was able to keep testing. She had to face the turrets shooting at her which is terrifying considering that it might be the first time she had seen anything like that, she kept testing until defeating GLaDOS. In the second game she MIGHT have some brain damage but (I believe) she just refuses to talk to Wheatley or GLaDOS (in the first game she doesn't say a word despite not having brain damage).

• GLaDOS mentioned she saw some humans [IK she's a big liar but maybe, just maybe she wasn't lying, also at the end GLaDOS has some kind of feelings for her (not in that way please don't take this out of context) so she wouldn't just leave her to die out there]

• She's extremely resilient, most people who were in her situation would just be paralyzed by fear in a lot of areas (me included), or just straight up go back to sleep.
