Yes, from the very beginning. Nefcy admitted that Star is based on her high school fantasies, when she used to go to school in top hats with plushies pinned all over her backpack, viewing herself as some kind of magical girl hidden in plain sight.
That's what the original concept of the show was going to be before it got retooled; the misadventures of a socially awkward girl who escaped into her head to deal with the fact that she weirded people out and didn't have friends.
Those traits got pushed off onto Starfan13 instead who is voiced by Nefcy herself. The show at its core is self-depreciating.
