being stressed (about the future which i may be not exist in)

i haven't been doing so good at classes, and don't even have a dream job !!!

just want to bed rotting but i'll be 18 and apply to a university then i have to take responsibility, PAY RENT - PAY BILLS - PAY TAXES...

ughhhhhh how to be a jouhatsu, i will disappear without trace and start new life in different country - that would be worse but at least i can do things i like and enjoy it.
