Login problem

I’ve just done something stupid ??

I set up two blogs on wordpress.com with similar names.

When setting up the second one it asked for a different email address from the first one.

I then logged in to the second one and changed the email address to that of the first one. As a result when logging in to the second one it now takes me to the dashboard for the first blog. If I try to login in to the second blog whilst logged in to the first I get the message “cheatin’ uh?”

I can no longer access the dashboard for the second blog.

Can anything be done about it. Can I delete the second blog without being able to login to the dashboard.

Here’s hoping?
