Logging in to WordPress.org website

I recently developed my site http://www.liveitactive.com. This morning I went to check out site stats, etc. and am not logged on. I went to wordpress.org and wordpress.com to see if I could log on. I also tried the wp-admin address that was given to me when I first started my site.

I am sure this is a silly question, but how do I log in to access my site dashboard, etc.?

Thank you,
M
