Help Me Legally Change My Name!

My name is Amy-Leah, well that’s my new name. I’m asking for help because in my life I’ve gone through a lot of trauma and had negativity that has been associated with my old name. It reminds me of everything that I was.. all of the blocks I had and all the failures that I had accumulated. It reminds me of scary things I’ve gone through that I would all together like to forget. I’ve never felt my old name was who I am. Why Amy-Leah? I picked the name Amy to honour my great nan who died when I was young. She was a beautifully kind woman. I added Leah because I like how it sounds! If you help out I will be more than grateful but I understand if not. I love you all and I appreciate your support! Thank you! ❤️
