i accidently closed my microsoft account how do i get to reopen it

I accidentally closed my Microsoft account and want to reopen it?  I can not use Windows Store in W8 without an account. 
also  i cannot install any apps in my laptop.

I am trying to log into my Microsoft account using my ***@gmail account, which is the account that I set the computer up with and also the account that I first used to set up my Microsoft account,

When I try to sign into my Microsoft account it tells me that the ***@gmail doesn't exist, but when I try to create an account using my ***@gmail account it says that the email address is all ready in use.

thanks for the help.
