You'll need to contact a Game Advisor, and after they prove that you are the owner of both accounts they can assist you with linking your Xbox profile to a new origin account.
You can reach a game advisor here: https://help.ea.com/contact-us click on the orange button on the right to start a new case, follow the instructions and when you are presented with a contact method I recommend that you use the telephone option and the “call me” option so you don't have to stay on hold for a long time. The call back feature available to North America, Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Hungary, Ireland, Italy, Netherlands, Norway, Poland, Portugal, Russia, Spain, Sweden, Slovakia, Switzerland, and the UK.
