Do you have a Simself?

I once made a sim that I intentionally created to have just some of my features and it had such a big impact on how I played that I never did it again. She is still in one of my saves and it's ok seeing her around, but I learned that I feel restricted with a Simself and have a real problem doing things I would not do IRL. I would also not be able to ever upload her, I would find that extremely awkward.
Obviously I don't have a problem with other players using Simselfs and don't think anything negative of it - just wanted to mention that, because my remarks sound a bit intense.
