None of us on this forum are doctors so we can't tell you what is going on with you. We can only give you our opinions or share our experiences. Your symptoms could be related to either or both conditions you mention, but they could also be signs of any number of other things as well. The ONLY person who can tell you for sure is your doctor.
Once you've seen your doc and if you are dx'd with anxiety, please come back as we can definitely help you with THAT! We may not be doctors, but we ARE anxiety pros!
There is an Asthma Forum here where you could get some good advice from folks who DO have it. You might want to stop by there.
I wish you the best
Peace
