I should mention, by accident, inadvertant, I never used a web based wallet hosting service. It was all local storage, not using any web/internet based hosting system. I didn't even know they existed when I mined it all those years ago.
Then the only wallet you could have been using that would have used a word list is Electrum.
Do you still have most of the words from the word list? If so, it may be possible to recover your Electrum wallet. If not, then you will need to find a backup of the wallet data file (or recover the original file).
