Marriage license signatures - help please

G

Can somebody ease my mind please... I got my ID when I was 16 and wrote my name in cursive cuz I didn’t know how to do my “signature” yet. I recently got married and I now have a signature. After I signed the marriage license the lady said that my signature must match my ID’s signature or we’re gonna go to court for like a year because my signature is my “identity” and they don’t match. Did anyone have a different signature on their license and ID and not have problems at the social security office to change your name or dmv, anything legal. Etc.
