Was My Account Hacked!?!

I was just surfin DP with my username "Coolalex" then all of a sudden I was logged out and could not login again with the info I know was correct, and it was saying my email was wrong when I tried to send my password back to my email.. And now my account has the signature avatar, and locations gone which were sold and there are posts offering to sell those spaces.... I THINK SOMEONE HACKED MY ACCOUNT!!
