You say it’s not anxiety with such confidence. So did us all who recovered from this. Idk how to convince people that it is. Because unfortunately there’s not this be calm no symptom relationship. You feel it 24/7. It’s atrocious. I get why you say it’s not anxiety. You look for something to credit when it’s not there and something to blame when it is. Was it the amount of water I drank, the position I sat, the food I ate etc. It is random, it had no correlation to anything in your day.

TO ANYONE WHO DOESNT THINK ITS ANXIETY WHEN SIGNS POINT THAT WAY, think about it this way. Mental anxiety do you think people get that after stressful events, or don’t some people get it just speaking to a new person, crossing the road, cooking a meal. These people aren’t much different to normal people. They feel fear and try to fix it try to avoid it try to reason with it. In the same way physical anxiety came in the form of a feeling, a very uncomfortable feeling. And you all who have this breathing, tried to fix, tried to figure out, tried to avoid feeling etc. this is why you still feel it. If you just let it be and live life. Your body/brain forgets about it. It’s not important to you means it’s not important to it.

I’m not a therapist or doctor.
This advice is for people with false shortness of breath who’ve been cleared for lungs/heart etc.

I wish you all knew how bad I was, that I’m not a different case. I couldn’t leave house for 6 months I felt like I was suffocating every minute basically. I hope someone else takes my advice, the hypochondriac health gaslighting scares me. Listen to your general doctor who has nothing to gain from expensive procedures done by consultants. Be wary of consultants just taking your money by telling you what you want to hear.
