As an only child I deeply relate to growing up lonely and taking little interest on other kids your own age, as you perceive yourself as to have maybe more in common with the adults you know. Turning into an adultified kid that cannot be perceived by others with the same seriousness. Also relate to the feeling of having to be the adult/bigger person/mature one at the same time that you feel like helpless victim with no outer comfort.
Your art is beautiful and full of personality, I honestly missed Chasity the next day too ToT and felt so compelled to know more about her!
