I’m seriously considering to quit my job / I have recently been thinking of quitting my job recently. My current job is consuming nearly all my physical and mental energy. I didn’t expect working as a teacher to be like this. The stress comes from both the school and the students. The school imposes an unreasonable workload on teachers and puts all the emphasis on marketing instead of teaching. Meanwhile, although some students are pretty nice and caring, others are nightmares. The misery this job has been bringing me is growing with each passing day, and I don’t think I can bear it much longer. However, I’m struggling to figure out what kind of new job I should try/look for, so there is still a long way to go.

I’m seriously considering changing my job. My current job is consuming nearly all my energy, both physically and mentally. I didn’t expect work as a teacher to be like this. The stress comes from dealing with both the school administration and the students. The school imposes an unreasonable workload on teachers and puts all the emphasis on marketing instead of teaching. Meanwhile, although some students may be pretty nice and caring, others are nightmares. The misery this job brings me has grown with each passing day, and I don’t think I can bear it much longer. However, I’m struggling to figure out what kind of new job I might try, so I still have a long way to go. Your use of "recently" is not right. You could say "I have been seriously considering...recently". Why are the two statements "the school imposes an unreasonable workload on teachers" and "puts all the emphasis on marketing instead of teaching" together in the same sentence? They seem like different thoughts. If there is something that links them, use an appropriate conjunction. If not, put them in different sentences. The second sentence could start with something like "Furthermore, ... I don't really understand what it would mean for a school to put an emphasis on "marketing". That could use some explanation. Good job, Claudia. The concerns you express are the same in many places. In the U.S. teachers have a high "burn out" rate. Teachers are expected to perform miracles. They are expected to push knowledge into the students' brains. But that cannot happen. Learning only happens in an atmosphere of respect. In the U.S. the teachers often do not receive respect from the kids, the parents, or the administrators.
