Assalam aleykom brothers and sisters

I have a huge problem and its tearing me apart.
I accepted Islam in 2015 and in 2016 I suddenly remembered that I wronged a person many years prior to Islam. This person may know or not know that I did this thing to him/her. Telling and asking for forgivness from this person may result in a lot of problems for both me and the person. If I do anything it might result in me going to prison and the person will be emotinally scared for life. I have blown this thing up so big in my head so I'm too scared to do anything and if I was going to do something I dont know what that is going to be. I have so much guilt and fear of the consequences. I dont want this person to take my good deeds or me receiving this persons bad deeds on Judgement day. What do I do???
