purely made up, but to write any character you have to have some reference point of understanding other people (or yourself). i think most often my reference points are other fictional characters that i like. cassia is yui from k-on, but just in the way that i interpreted her character and only the elements that made sense for cassia to have... a lot of my characters are written around feelings i can personally relate to a lot as well. they're all me, but not me at all. that's how writing is in general.
