Q: I forgot my security question and when I press send it by email it doesn't work please help me

It would go to a separate rescue email that is different than your Apple ID.

If you do not have a rescue email address (different from alternate email address) set up, you forgot it or no longer have it, then you will need to contact iTunes Support online: http://apple.com/emea/support/itunes/contact.html (select Account Security as your help topic) or by phone: Apple Support Numbers
