Yes, thinking about a disease can cause real physical symptoms and even worsen existing conditions, a phenomenon known as the mind-body connection, often seen in health anxiety (Illness Anxiety Disorder/Hypochondriasis) where intense worry triggers stress responses affecting heart rate, breathing, and digestion, but it doesn't usually create a complex, serious disease from scratch, though it can be a self-fulfilling cycle of real symptoms.
So, is it Your Mind Creating Symptoms? In one sense yes, but that's not the full story. If you have health anxiety your symptoms likely come from the mind, but they are still very much real. This is because anxiety affects both our mind and our body – with short and long-term effects.

Supplement options
Although further studies are needed, vitamin D deficiency has been linked to anxiety and depression. Supplements may help manage symptoms of stress and anxiety in those who are deficient. Vitamin B complex supplements may also help lower stress and anxiety levels.
