I hate bloody noses! Now, I have two sons and one has had chronic bloody noses. What was determined by his doctor is that he has allergies and at night, while asleep, would itch. Not even knowing it! So that his turbinates would become enlarged and inflamed. We did a nasal bath for him and then he started over the counter allergy medicine. Has worked well. Another son that gets them does so in dry air or post cold. Stress doesn't usually start a nose bleed. I'd look for something more going on with the lining of your nose. good luck
