Been having shortness of breath last 2 days.i can't breathe in all the way, what could it be? i have anxiety but this doesn't feel like that to me

See doctor: Anxiety can show up in many different ways and breathing issues can vary at different times and in different circumstances . However, to reassure yourself and rule out any allergies or any other,physical conditions, get checked. Also think about anything,that,is new or scary,over the past two days so you can better understand what might be happening.
