I actually haven't bought avoidant as an attachment style, or bought attachment styles in general. But I understand avoidance as a defense.
The thing is the avoidance started because people made fun of my parents, not because they made fun of me. But then I just felt uncomfortable in general with all types of displaying emotions.
After leaving my one real job, I was trying to work alone. Though I did get some gigs illustrating books, I didn't feel comfortable with my expressions. At the same time, I did a side project in my spare time drawing childhood themes. It's not very profitable because the coloring book trend was already about to end at that time. But I did it because I thought it would be beneficial for me to find my style long term. I used to have several books on Amazon with reviews though they are not available anymore.
It got repetitive after a while. But in the beginning, I got scared and almost wanted to cry every time I posted a new picture. Because every story has an element of real life. Either something happened to me, or something I wanted for myself. Feeling exposed. I thought then, I was no longer in an environment that would use it against me anymore. So after like 20 more times, I didn't feel scared anymore. As more and more people contacted me and said they like my expressions, I got even more brazen in the next picture.
Although people had trouble mistaking me as the polite customer service one. I was actually the selfish, arrogant, boy-obsessed one as in the pictures. But, well, I had to sell merch too.
So I wasn't always like this. It doesn't sound like much but it was a huge step for me. I know how an environment can change a person. But you can also find yourself again just by meeting new people.
