5. Depression vs. Anxiety
Depression and anxiety often go together, but they are different things. People can have both, but depression is more often linked with fatigue and low mood, while anxiety is a restless feeling of discord that makes it hard to calm down. Depressed people may struggle to get out of bed while people with anxiety may have trouble going to bed at all.
Hypothyroidism is commonly linked with depression because of its connection with low energy, while anxiety is a frequent side effect of hyperthyroidism. But because depression and anxiety represent opposite ends of the same pendulum, you can’t necessarily rely on having either one as a proof of a thyroid disorder.
