Breath.

[zippy]

The last 3-4 days non stop i have the feeling i can't breath or i am breathing too hard. The back of my throat feels like when you have been exercising or doing something strenuous. Every time i go anywhere or try to do something i start sweating and feel awful and like i can't breath but i can. It's not a panic attack when you start to hyperventilate it's there all day. I feel like i am never going to get better and it's my lung.

Sounds exactly like anxiety.

Its critical to point out, Panic attacks are usually short term and more severe. Anxiety attacks can last a long time and produce every symptom known to man.

Your anxious....Breathing isnt something you DO...it just happens.

I am getting it all day every day. I have no energy at all and when i try and do something i feel dreadful. It doesn't help that i have had a middle left back pain for 2 months either that is confirming in my head it's my lung.

I experienced something similar fairly recently. Persisted for a while. It has since disappeared and I feel fine. Must have been anxious/panicky.
