Can't catch my breath for over a week now, only when I first wake can I breathe easily

Can't catch my breath for a week now, only when I first wake can I breathe easily. Can anxiety cause this to last so long? Been to urgent care and going to doc today but curious of any one has experience such a long episode.

Also I have thyroid nodules and my ENT mentioned it might get harder to breathe but I'm hoping it wouldn't happen so quickly within a week and that this is just anxiety.
