A girl keeps repeatedly binge watches the same comedy show and binge eats the same thing. What's wrong with her?

[Anonymous]

She gets up, east and then shuts herself in her room in the dark and binge watches the same comedy show over n over again all day and night, regularly. It's been a year now. First 3-5 months she regularly ate momos...20 momos a day. Next 8 months she eats 5-9 chocolate bars a day... constantly. She'll melt it and eat it while binge watching the same show.
She does nothing other than that. She is completely isolated and has shut out her family. She stays in her room locked inside all day and night and always keeps the drapes shut and no light. She literally talks to no second person at all.
What is up with her?

What's her psychological issue or if anything else

no "wrong" she repeated the stuff she enjoyed.

She doesn't want to be bothered by you

I'm asking about her psychological state.

[Asker]

Don't answer if you don't have one

She seems happy to me
Or it could be depression but gorging chocolate like that isn't healthy

[Asker]

Okay

Autism

[Asker]

Nope. Her behavioral change started appearing serious in the last 4 years

[jahaims]

Unmasking and / or regression can occur with autism. Could be depression as well.

[jahaims]

It can also be autistic burnout

Nah doesn't fit
