Again if her mom is a controlling helicopter parent she will not be allowed out of her mothers sight or vicinity for extended amounts of time.
As far as we know, Autumn is isolated from others in person, which is why she thrives on positive attention and people wanting to be/see her friend. She doesn't have an offline life because she's alone, she doesn't have a permit or license so she is stuck in her home probably alone most of the day before covid hit.
She claimed her mom was going to kick her out on her 18th birthday, beacause she came out, during a pandemic. Then her mom doesn't and she never brings it up again. Which gives us at least 2 scenarios:
Autumn never came out to her mom because she knows her mom will take her only connection to the outside world.
Her mom more than likely knows she won't survive on her own and that's why she has yet to do anything about her. She also probably assumes Autumn is just trying to get attention and ignored her.
Also decided to share some close ups.
