If you have an email it'll be possible but if you don't, I don't think you can anymore.
Sorry for not being able to help!

I'm not sure about this because I've never deleted my account before, but I think you can still reactivate it at any time as long as you enter the password?

Q: How do I deactivate my account?

A: You can deactivate your account in your profile settings which makes your stories, blogs, and profile completely inaccessible. Comments are not currently removable in this manner but you have the ability to delete them manually yourself. To reactivate your account, you can log back in.

From their FAQ page. So if you deactivate your account, you can still log back in.
