Shakespeare once wrote : "What's in a name? That which we call a rose
By any other name would smell as sweet."
Personally I don’t really believe in the ‘new identity’ part of your considerations. You will always be you,no matter how many times you change your name.
I’m also really curious about the ‘hating your name’ part. Forgive me if my assumption is not correct - I only mean to do good and have no intention to offend you in any way - but to me it feels like you are struggling with issues that go far beyond just your name. (That’s ok - I think everyone does) Changing your name is not going to solve the things you’re struggling with.
Learning to accept that what is, is and working on living in peace with yourself and who you are - it’s a though lesson to learn. I’m speaking out of personal experience.
If you feel it will help you move forward, then all the cons you listed are not even important enough to consider. Then you should go for it, and don’t let nothing hold you back.
But the fact that you think that those cons are hurdles you don’t want to take, gives me the impression that deep inside, you know changing your name will not create the effect that you want it to.
You know, your name is not important, what’s important is who you are as a person, whatever your name is. Facing life and dealing with things you don’t like by accepting them, makes one a stronger person.
Maybe I’m completely wrong, if so, please forgive me for that. Also, it’s hard to explain what I mean in a language that isn’t mine. Still I hope I have been able to expres my thoughts.
And whatever you decide, you have my support.
