Perhaps talk to your Dr about trying a different SSRI, possibly sertraline or citalopram may help with the anxiety. Fluoxetine can be quite stimulating in some people which can make anxiety worse.
Don't just stop your meds though as you may get a withdrawal effect.
As for education, ask for help, are you able to afford a private tutor, could you change school/college, are you sure you have picked the best subjects to study, all this really needs to be discussed with your personal tutor.
And people do care. There is always help available, but with so much going on, especially post-Covid, you might need to shout a little louder for it.
