How do i know if im having anxiety or if something is really wrong?

Anxiety: This requires a history directed at your symptoms with examination and appropriate laboratory to exclude organic cause for your complaints. Then and only then can one move to alternative diagnosis.

Anxiety: Anxiety is a natural and normal response for all of us.When it goes beyond out control it's disabling discomforting and makes it difficult to continue any normal activity at that point treatment is indicated with therapy only or in combination with meds if its bothering a lot please consult a psychiatrist or at least a therapist all the best.
