Followed in target by shop lift prevention! What next?

So i was in target and i was attempting to steal a pair of $30 headphones. Before you tell me i shouldn't steal trust me after this i will never do it again. They followed me around speaking into their intercoms and i was so scared i just threw the headphones away half opened. They didn't stop me from leaving because my sister draged me out but i'm scared about what will happen next.I've probably stolen like over $300 in the past 3 to 4 years and i turn 15 in march.
