Almost 18, f**k.
I'm almost turning 18 and I'm not yet ready to be an adult. Life is already hard enough as it is, and I don't want the extra responsibility of being an adult added on top of that. My dad already make fun of me not having a job or going to school and I think my parents are going to get even worse the older I get. I dropped out of middle school once and twice out of high school. My dad says I'm lazy but I have serious trouble doing anything, and get serious anxiety even thinking about doing something. People are prob going to get real judgemental and tell me to man up and get a job. Autism symptoms are also getting more severe: I get panic attacks when my brother bring his girlfriend over. Avoid her like the plague, I don't want anyone to see my face. I can't do a lot of simple tasks I used to be able to do. Hard time communicating with my parents which is a pain in the ass to deal with. Is this what it's like to be an adult on the spectrum? life is such a f*****g dissapointment.
Not many people are ready to be an adult at 18. Nobody expects you to be a perfect adult by that time. In most of Europe, one remains a "youth" until age 26. In the US, people stay on their parents' health insurance until their 26th birthday (if they are living with the parent).
However, it is expected that you start progressing towards being an adult. And you are expected not to act like a stupid kid to others (i.e., by teasing them, bullying them, etc). It is expected that you conduct yourself like a decent person in a post-secondary school setting, and among your friends and family as well.
It is the "beginning" of adulthood, really.
But you have higher expectations as an 18-year-old than you did as a 17-year-old.
