Am I Okay

When people as "are you okay?" what does it really mean?
People have been noticing that I haven't looked to happy. Can they really tell.

Right now, this second, this day, this week, no, I am not okay. Thanks for asking.
If you are going to ask how I am feeling and not even try to do anything about it, than save your and my time and just don't ask. I personally don't know how to tell my family that I'm not okay and that I need help. I need it soon but how if my response to them is always, "yeah I'm fine" or "I'm doing well".

I'm far from "okay", and unless you really want to help me, don't ask me the question.
I don't know how or what I'm gonna do but the more I wait, the worse it gets.

I don't know if any of this makes sense. It does in my head. Good Night....I guess
