Objective
Clarify the meanings of these expressions and the functions of 'ir'.
¿Cómo te vas?
I suppose this is the reflexive form 'irse' and it means "how you leave" or "how you go".
¿Cómo te va?
I heard this is equivalent with "Cómo te va la vida a ti", however not sure of the function of 'ir' here. It seems 'ir' has a meaning of 'cause an effect' such as "What has the life done to you", but not sure. Checked Wordreference but there seems to be no such meaning explicitly.
Also when I was in hospital in Colombia, a doctor asked "¿Cómo va?" after a while when he gave me an injection. I suppose he asked "How is the treatment working?" or "How did the medicine work?". Is it correct?
Kindly suggest what is the function of 'ir' here.
¿Cómo se va?
Is it equivalent with '¿Cómo se va la vida a usted?', as well as '¿Cómo se va (para el estación)?' asking how to get to somewhere depending on the contexts? Can I say "¿Dónde se va esta calle?" to ask "Where does this road lead to"?
Kindly suggest what is the function of 'ir' here.
