See your doctor: You are on lithuim with often electrolyte abnormal and dehydration. If no medical issues your psychiatrist will help manage your depression.

Need antianxiety med: You are not on any medication for anxiety. Your hyperthyroidism must be adequately controlled as well. Ask your doctor for something for generalized anxiety.

Depression: Yes depression could cause these symptoms. Make sure you consult with a mental health professional who practices psychotherapy as medications alone are limited in effectiveness. My best.
