I feel like a bad girl, not pure at all. How to change it back?

You have realized that you are like a bad girl, and now you just like it, not really. Don't give yourself too much psychological pressure. If you feel that you have done something wrong, then don't do it. Do what you think is right.

Tell people close to you what you think. The authorities are confused, and the bystanders are clear. Don't fantasize about yourself, and don't think things are too complicated and terrible.

Come on!
