I always used to nick stuff from shops, was good at it too.
I don't anymore and don't feel it is a good thing to do.
I don't know if it is a BPD thing, but doing risky stuff is so there is probably some connection.
It is good that you feel guilty (as it is wrong) but as long as you are aware and learnt from it, I don't think it is the crime of the century

just be careful xxxx
