What if I don't see my profile picture under My Content => Page?
In this case it means you had previously deleted the block of your profile picture.
To add it back, click on the first "+Add Block" you see at the top of the page, and then choose "Profile" among the list of available blocks.
This will restore your profile picture block, and then you can edit as described above.
