Can't reach my account don't want to loose content

I have used my email with Facebook login before and after a while I forgot and entered with my Google account with the same email. When I reset my password it automatically connected it with the second? Account so now I can't reach my actual account with all my lists. It's open only at my phone app and I can't find any other way to recover it and enter from my computer. (I know my actual accounts' username)
