I absolutely appreciate your openness in sharing this 💜
The protagonist was crafted with several things in mind. I wanted them to communicate these personal issues in the context of someone you might meet/know, or also someone you might be. I don't know how much of the game's second half you played, but that section focuses on also communicating the fact that everyone, no matter how they feel and act, is human, is of equal importance, and is deserving of equal compassion. Mental struggles can create problematic people, but they do not have to define that person, and it's very important to remember the human beneath the actions. True Colours aims to explore this, and it does have several heart-warming endings that show the protagonist improving their perspective and mental health due to the personal revelations they have.
I'm glad that you saw something real in this game, as I was very much aiming for authenticity, and if you do play any more, then I hope you really enjoy the emotional relief of the good endings 💜
