Call SWTOR support using the appropriate number from this list: https://help.ea.com/en-us/help/star-wars/star-wars-the-old-republic/swtor-support/
Of course you'll have to provide identification, so knowing the answers to your security questions would be optimal, if you don't know them out of your head, maybe you'll guess/remember when they ask you the questions.
