You can’t really cure a personality trait, but you can learn to manage it by becoming aware of what triggers your behavior, such as high-stress environments or feeling out of control, and what makes your symptoms worse. Then you can address those issues directly and reduce neurotic behaviors. There is no specific diet for people with neurosis, but the link between nutrition and mental health is well known: What you eat feeds the way you feel. This is largely because the majority of serotonin, a neurotransmitter critical for emotions, is produced in your gastrointestinal tract. Add more fresh, colorful foods to your plate and consider talking to a dietitian to come up with a healthy diet.
