There's always a reason for these behaviours.
I shoplifted as a teenager. It was make up, hair colours. I felt (and recognise now as a 50-year old) deprived of such items as my stepmother was puritanical. But I remember the feeling clearly. I got caught.
I'm aware of a friend's friend who's a regular shoplifter. We had a discussion surrounding her behaviours. She was indifferent about her acts and I drew from her comments that she felt a sense of entitlement and because it was large corporations it didn't matter.
OP, I wonder what you're reasoning is for posting here. Is it because you want the shame to make you feel better? Knowing you'd receive mixed reactions to your admissions, I wonder which ones do make you feel shameful. I don't think you're brave or courageous or have a need to 'turn' your life around, I think you're posting here for something and I can't put my finger on it.
There's something much deeper than unhappiness, I don't see or read a sense of entitlement, I see a habit that you've grown out of. It's clearly not a fear. It hasn't taken you ten years to think of the shame you'd being on your children. Or your chap.
I don't read either that its been a thrill. If you're surrounded by your ill-gotten gains, you're not ashamed. You're sitting among these items.
It's almost as though it's a comfort thing.
Interesting - I'll than you for posting. But I'm very intrigued as to what is behind your actions, why you have stopped and yet you still keep the items.
