Question

hope you are mentally ready to come over

Answer 1

Definitely more of the context is needed, but when you tell someone to come over, you tell them to join you in a place where you're (or gonna be) already present as in,

"Hey Meg, there's a party at Greg's. Are you coming over?"

"Why don't you come over for dinner this weekend? Grandpa's gonna be here, too." 

I'm not really good at translating but I'll give it a shot :-)

امیدوارم از نظر روحی آمدگی اومدن (به اینجا) رو داشته باشی.
