I try to breath the air more often,but it seems like i breath you more often

My breathing seems to be shallow.
And everytime i breath,
I feel the pain.
Breath in.Breath out.
So,i took short breath to not feel it.
Yes,it works.
But,it's not enough for me.
Breath in.Breath out.
So tired.So restless.
Deep black shadows under my eyes.
Am i dying?
Deep breathing.
Ouch.
