Annoyance in Russian
I don't know how to properly sound annoyed in Russian. In English, if someone was telling me something I already knew, I'd say, "I know I know!" How would you say that in Russian? Would it be, "Знаю знаю!" or "Я знаю я знаю!" When I don't care about something, I might say, "Yeah, whatever." How would you say that? Any other annoyed phrases in Russian are welcome.
Other annoyed phrases may be:
Да мне без ра́зницы! - I don't care (if this or that happens / what to chose)! / All the same to me!
Меня всё достало. - I am fed up with everything.
Отстань от меня. / Отвали. - Leave me alone / Get lost.
Да Го́споди! Ты надоел мне! - For God's sake! I am fed up with you.
Блин! - Universal informal euphemism to say when something is not happening as you expected. Sh*t. Literal translation is 'pancake'.
Хватит (уже)! / Прекрати! - Enough (already)! / Stop it!
