It might help if you spoke to a therapist about it.
They can help you sort these things out in private.

I know in my past, I was exposed and taught by a parent to be shifty, lie, and try to get away with things.
For years, I had this side to me.
I realized that it was something that I was taught and some part of me thought that I was suppose to do it.
Or that it was the way to be - but I hated it.

Once I looked honestly and openly about it, I was able to change and be someone I like.
