Even with the use of appropriate medication, appropriately administered, a person can have a bad attack, poorly responsive to the meds. Your description strongly suggests that your asthma is out of control and that you should seek medical assistance without delay.
Given your multiple allergies, it is possible that your immune system has been overwhelmed by unusually high concentrations of one or more of these allergens.
If not already seen and treated, you should definitely see your doctor and, if he/she is uncertain about the cause, together you should request consultation with an asthma specialist (Allergist or Pulmonologist).
