I would like to delete my account. I checked the help section, which instructed me to go to my profile and click on 'Delete Account' under the "actions" section on the left. However, I am unable to locate both the "actions" and the "delete account" link
You can not delete your account.
Abandon it if you don't want to use it.
You can go to profile page, Account related settings, click on secret question, it will trigger an account lock, then you can abandon it without fear that someone will hack your account.
PSA: ACCOUNTS WILL BE LOCKED IF THE SECRET QUESTION IS USED TO RECOVER IT
