I dearly wish I hadn't clicked on this thread!
OP, I would look elsewhere if the tutoring she offers has anything to do with English language.
It's a glaring error. I don't flatter myself that my own written language is perfect, but this isn't an error I make.

'Myself' is correct in this sentence and (arguably) sounds better than 'me' would. I was taught in school that 'xyz and I' or 'myself and xyz' was the correct way to say this, not 'me and xyz'
The trend to use 'xyz and I' or 'myself and xyz' is a poster child for what is called hypercorrection, which is the technical term for grammatical mistakes made through applying grammatical rules incorrectly, as opposed to mistakes made through ignorance of grammatical rules.
It doesn't sound better, it sounds like you (like many, many, many other people) were taught that using "me" was the mark of the uneducated and to be avoided at all costs. I believe it all started in reaction to the trope in films and books that working class characters used me exclusively in speech. In response people have tried to distance themselves from the mocked speech pattern so far that they're avoiding me when it is the correct word, and I'm not sure how the trend can be halted now.
The word myself is a reflexive pronoun, to be used with reflexive verbs, e.g. I wash myself. It's really not an elevated, formal synonym for me.
