How do I delete facebook from my computer?

[L]

You can still gain control of your Facebook account and once you do, its up to you, what you want to do with it.

click on "forgot password" just below the password field, then it will tell you to enter your user name, phone or email address.

enter your " email id " there and click on search then it will show you the Facebook account linked with that email id.

click on "This is my account" and then choose "Email me a link to reset my password" and then click on continue.

open your email id and then click on the "rest password link you received from Facebook"

And then reset your password and loin into the account and whatever you like to do with your account.
