All games gone

Hi, i did something today where i didn't know it would have this effect.

I had an already existing account with the same email as my google account. So this time today, I logged in with my google account instead of doing it by using eail and password. Now i think the account merged and all my games are gone. is there a fix? 

in the left bottom corner in the updates menu, I can still see my games that have had an update... So thats still there but the games itself are gone.

Help me out! :(

Kind regards
