I don't know if I'm correct, I ain't a doctor, but if that isn't depression maybe it's Autism?Autism is less diagnosed in women cause it appears differently in them compared to guys, so if that wasn't suggested to you before that might be the reason? I heard about autistic people who may hit themselves when frustrated, and (never heard about screaming, but) repeating the same word is something common. I'm autistic and also daydream excessively, but I don't know if that's has to do with it. Lacking some form of control can be a source of frustration for autistic people, and they have a different way of perceiving things and understanding the world, so it may be needed another way to explain something. Regardless, check the symptoms common in women.
If that isn't the case, it's worth remembering that depression isn't necessarily sadness, it can also be dismotivation and fatigue.
I repeat, I ain't a doctor, I'm just autistic and have an interest in my own condition and how it appears in others like me. I could be biased.
