Will i be forgiven?

I believe I was 12 or 13 years old when I saw a TikTok about a whisper method where, if you whisper someone's name, they will think about you or something like that. I don't quite remember, but it was from a fellow Muslim creator. I didn't have much knowledge back then and didn't know that it could count as sihr and shirk. I don't even remember if I did it or not, but I feel completely lost. I believe in the mercy of Allah and am aware that He will forgive me, but something inside me just needs that clarified.
