What illnesses can i get if i am stressed? and what is wrong with me i am so worried what can it be? and what can i do? help me so worried and scared

Anxiety disorder: Stress itself doesn't cause any illness but i don't know any illness that's not made worse by stress. I don't know enough details but it sounds like the illness you are suffering from is anxiety itself, which can, of course, be serious enough. Various pharmaceuticals may help but so can supplements, herbs, exercise, relaxation techniques, homeopathy & counseling. I advise seeing a holistic doctor.
