I constantly use social networking sites, and i'm always getting my emails sent to a couple different emails..

One of the sites randomly forgot my password and I went to reset it to my email, to find out when I try to log on that someone has been trying to type my password in wrong multiple times and it has been "blocked". By this point I just thought it would be fine to send the reset password email to my alternate email address associated with the first email account, and I tried to log onto that account afterwards. 

It said "this email does not exist" it was a live.ca one, and the first one is hotmail.com. 

I'm not sure why my email does not exist and I can't get to any of my emails. 

What do I do? also I've tried multiple times with emailing myself at the two emails and it says the delivery failed?
