I feel threatened by women prettier than me
Why do you feel threatened by prettier women?
They know that they are prettier than me and I feel bad about it.
It is fine feeling a bit intimidated, but you can't let that consume you. Just work on improving your own life.
I can't, they are so much better than me.
There is no reason to be intimidated of these people. They are just trying to live their lives, you should do the same. They may not even be aware of your existence.
