Need a new name

As the title says, I need a new name. I (22F) am named after a country. I can’t stand it and all the bullying I get about it, and my middle name is just not fitting so I can’t use that. There are also absolutely no nicknames you can get out of either one of those names. I’m thinking about changing my middle name to something I like and using that like personally/professionally and keeping my icky first name just legally, just in case. Help me pick something out!
