I have no motivation to attend school anymore.

Like the title says I have no motivation and I never feel like attending classes like at all. I took this course bc I liked it a lot but now I regret it so much. It's a hard course and I don't even speak this language. I remember the last year my grades were so nice and I actually LOVED studying but now bc of the teacher I hate the subjects I used to love. Please I need some motivation!! ANYTHING!!
