Biggest regret I have ever felt in my LIFE!

My baby’s name choice is the biggest regret I have ever felt in my life. She just turned one and I have been feeling this way since about 2 weeks after she was born. I just felt like her name was not the right choice for her. I thought it would get better with time, but it hasnt. I know a lot of people will say “its simple, you can change it” but it really is not that simple. Mainly because no one outside of 2 of my closest people really know about my true feelings towards her name so it would be a complete shocker and everyone would think I am crazy! I also have everything of hers monogramed! Her name is literally all over the house (in attempt to fall in love with her name) but for some reason, I just cannot accept the fact that I named my daughter this particular name. It has led me to fall into depression and i constantly have these obsessive thoughts of how big a mistake i have made. It has gotten so bad that I started to take Zoloft for my anxiety and depression. I dont know what to do. I thought I would get over this feeling but its been a year and I still feel the same. I dont want to feel like this my whole life. Any advice would be extremely appreciated!
