Suffocated

Do you have times when you just feel that you are suffocating?
That you are trapped, confined and that you are trying hard to breathe as normal as you can but in your heart, your body herself, knows that every time you breathe, you are grasping as much air as you can get, but you just cant seem to get enough no matter how much you had taken in. Your mind cant think properly, either because of lacking of oxygen or that purely, you are delirium. A strong urge of just to stand up and leave seems like the only option to, break out of this suffocating situation.
But rationally, somewhere in you tells you that you cant, you cant just leave like that, you simply cant leave. You struggle, whether to get air or to think properly, it doesn't matter. You will try fidgeting around to find a better position to reposition yourself and at the same time you start wondering about possibilities, of what will happen if you get out this instant, will I feel better? Where should I go? What will happen if I have gone? etc.
These action-less and unnecessary thinking dies down and arise up and dies down again repeatedly. Like a vicious cycle, a loop with no false command to it and that it will go repeat itself over and over again, countless of times.
But, there, in fact, had no option in the first place. You are suffocating because you know you cant get out in the first place, that you dilemma was needless. The conclusion is already there and yet you simply didn't had the heart to accept it.
You start to be irritated at every single thing. Blaming everything and anything. Faces, people, their voices, laughter, the tiny and slightest movement they made. All of those, you just wanna either shut them out or leave the place and away from that all. It was probably aren't their fault, you know it. But they will always be wrong to you. They are the cause. For if they are right, then what am I?
A failure to being with? A runner? A loser?
Then what am I to believe in myself when I am wrong myself?
Is this about self-esteem or is it about existence of self or is it about a crazy person and her whining or grumblings?
It is up to you to think what it is.
But if you once felt that way then please reflect on it and we can discuss on it.
