Honey, take care of yourself well or i will get angry.

Hello,

When talking to a girl you like when she is ill, is it ok to say "Cолнышко, береги себя хорошо или я рассержусь :))" might have a jokey way? I mean i want to mean it in a jokey way and show that i care about her.

I am not sure of the "я рассержусь" part of the sentence. It might be a kind of anger that might scare a girl away? Ofcourse i do not want this to happen..

Can you think of a better form of saying "take care of yourself well, or I will get angry" ? I want to have the sentece to have both a jokey meaning and to show the girl that i care about her ?

Thank you. :)

I think you entering a slippery road where language meets culture.
IDK if it's ok to say "Honey, take care of yourself well or i will get angry." in your culture but I kinda doubt that it's gonna be appreciated when you say it in Russian to a Russian.
Just my 5 kopecks.

Well in my language it is possible to say it in a jokey way. But if it is not posdible in Russian. I will ofcourse wont use it. Thanks for the warning...
