Is there a way I could be forgiven if I intentionally eat non halal meat

At the age of 16 I had this one friend in which we both didn't really think about our religion. One night we were at her house and we ordered food from a place that wasn't halal and I'm not saying it was her fault because I was fully aware of my actions and I knew it was haram yet I still did it but I sorta felt as if it was peer pressure from both of us. A year has passed now and I've basically lost contact with her but I've been giving that day a thought and I've never ate unhalal meat again but I regret that day so much and wonder if I'm gonna be punished for it even though I wasn't that aware of the punishments of doing haram things. Also I wanna know if there is a way that I could ask for forgiveness about that specific reason. Any sort of help is accepted thank you!
