HELP! Username issue, no dashboard

My main website is http://www.theukthroughmyeyes.com. When you go to the site all looks normal.

I also own three closely related sites – http://www.ukthroughmyeyes.com, http://www.theukthrumyeyes.com and http://www.ukthrumyeyes.com.

I can see my username as it shows on my last post. However when I put my user name on my login it says it doesn’t exist! I document every time I change a username or password.

So I put in my email and it doesn’t show it. I use another email and it resets my password for one of my secondary sites. I cannot get to the dashboard on http://www.theukthroughmyeyes.com.

How do I resolve the issue with my username? This is crazy.
