I forgot security questions to help me

Well, now everyone on the internet knows your Apple ID and password so you really need to talk to the Account Security Team. Start with 1-800-MYAPPLE.

This is a user-to-user technical support site, Apple security staff is not here. And they would not tell you the questions if they were, you could be anybody.

Call AppleCare and ask to be transferred to the Account Security Team. This will take awhile and be aware you can turn off the hold music if you wish.
