Do you think she’s trolling us with this “overachiever” crap?? Because if it’s actually genuine then I’ve never known anyone to be so up their own arse as she is. I might be blind but I don’t see any overachieving?
I think that it is possible that she actually believes that she is an overachiever.
I have a childhood friend who is very much like her and believes that she is working very hard, while she actually is not. She is constantly moaning about how much she has to do and how busy she is, how she is struggling with deadlines, how work piles up etc. but when you start to actually look at it closer, it is clear that she spends more time moaning, worrying and complaining than actually doing anything about it. She even lost a job because she never got her work done on time and even then she was mad at her boss, not at herself. Now she is probably about to lose another job for the same reason.
In my friend's case, I do believe that a lot of it has to do with her having anxiety, which means that she spends most of her time worrying about her job, not actually doing her job.
In Amelia's case, I don't know her well enough to make guesses about her mental health.
