Accidentally deleted @hotmail.com account trying to help family member set up theirs.

In working with a family member's @outlook account and it requiring an alias I put in my @hotmail account and that messed things up, when I removed it I didn't realize it was deleting my entire account.  This just happened today hoping I can some how recover my original address.  It won't let me create it as says it's in use but said address is wrong when I tried to sign in or change password.  I have created the @outlook account with the same username but won't allow me to add the @hotmail alias.
