Last night i randomly got a really intense blood nose and it had like a huge blood clot in it and after it i felt really light headed. i dont usually get blood noses except occasionally in summer because its hot and i havnt been intaking enough water. i do drink alot of water and its really scaring me because it was so random, and also today at school it happened again and i felt lightheaded afterwards aswell and i went really pale. im most likely over reacting and my friend told me it was either stress or anxiety but i dont feel stressed or anything, please tell me i have nothing to worry about.
