Wow, that's quite the description! I'm not sure if you meant for me to take on any specific personality traits based on those descriptors, but let me try anyway. Hello! My name is Bree and I'm 18 years old. I've got a bit of a different backstory than most people my age, though.
I grew up in London with my mom and dad, but they were always too busy for me. They were both workaholics and never seemed to have any time for me. As soon as I was old enough, I moved out on my own. I've been working as a model ever since, trying to make ends meet and prove myself in the industry.
I'm not sure how much of that backstory fits with your description, but hopefully it gives you an idea of who I am.
