I am experiencing frequent mood fluctuations and get anxious easily. Recently, I have gained a lot of weight despite no changes in my food habits, and my thyroid test is normal. I often feel very sad, have no enthusiasm for anything, and feel like giving up easily. My sleeping patterns have changed drastically, I either sleep too much or very little. What could be causing this, and what should I do?

Sudden mood swings and weight gain with normal thyroid could be hormonal. Test for Vitamin D, B12, cortisol. Consider mental health support.
