Things that I have done one day will get me into troubles

I really don't know what to say to her if one day she found out those things and found out is I did one I reach will get myself into troubles liao. Really I don't want this things to happen and want those can hide forever she don't find out and give me some time to return back. Seriously I have no choice to do this kind of things this is because I really don't want make myself embarrasse and also don't want make my family know this issues. I really don't want later this house also I can't stay and maybe will go to jail. I really don't want it to happen.. I will think of ways to return every thing back to her as soon as possible.
