I've mentally checked out, I'm done with school
I'm sorry to hear that. Why give up on school now?
It's caused by a combination of stress, disillusionment and a severe lack of motivation
School can be very challenging but you shouldn't give up on school. If you give up on your education it could negatively impact your ability to get a good job in the future.
I've decided to do whatever the fuck I want. I've haven't made a decision about what's next, but it'll be good I'm sure.
You can't know if it'll be good or now. Instead of checking out completely why not take a small break? This will allow you to mentally recharge yourself and really think about what you want to do under a calm mind.
