Ask in a way that you're most likely to get what you ask for. You are worthy of respect. A respectful attitude honors asker and grantor. A respectful attitude is not self-degrading. If you don't like your name change it.
Many people go through life hating their names.
A name is a word that holds some power over your life. It's an easy matter to use a different name. People may resist the change. It violates the rules of a relationship you've established with people. In time your new name will be accepted.
