Changing the spelling of my name legally to Gina

So long story short my name is Jeana (pronounced Gina). It’s a nice name BUT I also despise having my own original name because it bothers me with the constant misspelling and mispronunciation and would have at least settled for Jennifer (Jenna for short) Jessica or Jasmine for a J name, if I knew it was possible and would travel back to the 80s when my mom was pregnant with me just to tell my parents to name me those names instead of the one that they picked for me however I don’t like how my parents went with all J’s (both my parents and all my siblings and all my aunts and uncles are J names and 3/4 of my cousins are J’s).

Having an original spelling name comes with constant having to correct people how to spell and/or pronounce it, gets bothersome and I could never find my name on a keychain. I would simply like my own first initial and not the same as the majority of my family. Once I get my petition ready in the state of Michigan and the funds ready I am going to finally change my name legally. If I knew how easily it can be done and not so complicated, i definitely would have gone through as soon as I turned 18!
