What do you think of me creating another version of myself?
What do you mean by "another version of you"?
It's basically another persona that I put on when I want to object to doing certain things.
Wanting to have the confidence to say no is fine but creating another personality just so you feel comfortable doing it isn;t being true to yourself. You should try to find the courage that the "real you" has and use that instead of creating another you or you may have some psychological problems down the line.
I'm going to see a therapist.
I hope that talking about things will help you. You should be comfortable just being yourself in life.
