Golden Rule: NEVER Ever Give Anyone Else Your Login Info (User and Pass)... Never!
We tell people not to do this... SS is not proof of anything man...
If I tell you not to jump from a building then you still do it anyway... don't come ask for my help after...
It's sad what happened to your account but this should be a lesson to EVERYONE that shares account info...
You can use Lost Password:

Your pass will be emailed to the email that account was made with... then u can log back in and change pass again... but your characters and items will not be retrieved.
