It's a weird process to go through, renaming yourself. From a sociological standpoint, you could have been given any name at birth and right now it would sound perfectly normal to you, but the odd thing is that when switching names, it's not as if you can just pick another one at random and just as naturally learn to associate yourself with it. Some sound right, some sound wrong. But enough of that.
I picked a name at first which was good enough, but on the understanding that it was a placeholder. It was a fairly common name and one which sounded similar to my male name, and consequently it was a fairly easy jump to make in terms of associating it with who I am. It was more like jumping from Harry to Harriet (not my real name, just an example), rather than from Harry to Sparkle Forest. It grew on me too, and I didn't really feel the need to change it after living with it for a while.
My actual female name is one that sounds kind of similar to my male name, but has some input from relatives and friends. It fits. It has some meaning behind it. It's still simple and plain, and it's also age-appropriate (I checked baby names from the years around when I was born, because that's what girls my age are supposed to be called.) There's nothing more weird than someone young with an old person's name or vice versa.
So yeah, it's a complex process, but it doesn't have to be permanent until you're ready for it. A temporary name is perfectly fine for now, and you might just find that it fits after all.
