@arcana @lucy @gray “myself” is correct here (reflexive object pronoun)
you wouldn’t say “I can’t cook for I”
and no, you don’t switch to I just because you bring in another person. grammar doesn’t care about the number. what matters is, are you doing an action (use “I”) or is that action done to you (use “me” or “myself”)? then, is someone else doing it to you (use “me”) or are you doing it to yourself (use “myself”)?
