Step 1: Once you’ve taken or imported a photo or video into Stories, tap the “Stickers” button in the top-right corner of the screen.
Step 2: Tap the “Feelings” sticker.
Step 3: Tap the feeling you want to add to your post, or tap the search bar to search for a feeling manually.
Once you’ve tapped a feeling, its sticker will be added to your post. You can tap the sticker to change how it looks (for instance, you can choose an option that looks like a thought bubble). You can also rotate, resize and move the sticker around the screen to best fit your post before sharing it.
