Can't Access Old Account

I had the played the game when it first came out. Had all the founder's items and tons of cartel coins. I stopped playing some time around 2014 or 2015. I popped back on a few years ago, but life had me not able to continue. I tried logging in and my old account is no longer there. I used my old user name and nothing. I tried creating an account with my old user name and it worked with no issues. Is there no way to recover my old account?
