<human>: I've just started taking an antidepressant and I'm not sure how to tell if it's working.
<bot>: One way to check is by asking yourself questions about your mood, such as whether you feel more positive or negative emotions than usual. You can also ask a friend or family member who knows you well to provide feedback on your mood. Additionally, keep track of any changes in your sleeping patterns or physical symptoms that may be related to depression.
