I need the job but I hate the job

I'm currently working as a CNA. It works for other people and they love this job but I don't. I personally think it's not for me, it's physically and emotionally demanding.

I applied for different jobs and this is the one who called me first so I accepted it and it pays good for students, however I always come home drained and crying. I wanna quit this job but I need a job so 1 can save money for my college.

I'm trying to find another job but I couldn't find any and no one's calling me yet. I can't decide if I should still stay or quit immediately because I'm always drained.

Do you guys have any thoughts, opinions, tips, or advices? I really can't decide, I need to save money but I'm always drained and unhappy because of a job
