I can understand how difficult it must be to experience constant mood fluctuations, insomnia, and headaches for the past three months. Lack of sleep can significantly impact your emotions, making mood swings worse, while prolonged stress and fatigue can trigger persistent headaches. Given that this pattern has continued for months, it’s important to look at possible underlying causes, such as stress, anxiety, nutritional deficiencies, or even hormonal imbalances. Fasting can sometimes affect energy levels, hydration, and blood sugar, which might be contributing to the intensity of your symptoms. But the core issue—insomnia and mood instability—needs to be addressed holistically. To improve your condition, we need to work on regulating your sleep cycle, managing stress, and addressing potential physical triggers. Cognitive Behavioral Therapy for Insomnia (CBT-I) is highly effective in breaking the cycle of sleeplessness and can also help stabilize mood. Lifestyle changes like consistent sleep schedules, relaxation techniques before bed, and proper hydration during fasting can make a huge difference. If headaches persist, identifying triggers (such as dehydration, screen time, or tension) will help manage them effectively. I truly believe you can feel better with the right approach.
