Aw, i do feel bad for the OP, it's obvious she is tired of something at her job.
//"You say that I rarely talk much.
You don't talk to me neither."//
You do not wish for them to talk to you, or you do wish they would talk to you?
At any rate, imo, there is a difference, between being a quiet person, and like, someone who can't occasionally smile now and then, til everyone figures out who they are.(a quiet person)
All creatures have body language, and an immobile face, accompanied by zero verbal participation could indicate, or could be mistaken for signs that one is upset, annoyed, etc.
that is why they are all asking you.
So, if that is NOT the case, then no harm in throwing out an occasional smile,
every once in a while, just to help your coworkers sort out you are quiet
, but, not unhappy
. Otherwise, it might be, they have zero feedback from you at all, to allay their worry you are upset. but, probably, overtime, they will learn who you are, and stop asking you how you are.
Maybe no words even req'd, but, an occasional smile
could help. If they saw an occasional smile (even if remark was not hilarious) they might stop worrying something is wrong/you are sad/you are upset, maybe if you smile now and then, they'd stop asking you questions which you find annoying. then maybe you could get the 'room' you seem to desire.
I'm only guessing, but, i imagine the people asking you if you are okay, had good intentions,
even if the result was you felt annoyed by the questions, i bet their intent was good or kind. I bet the last thing they wanted was to annoy you, i bet they genuinely meant well by asking. They were probably trying to make you feel "included" or cared about, even if it landed wrong in your ear.
