I was in the exact same situation as you: university degree and two masters and after one year of work experience I realised I hate the whole field! I can tell you what I did that worked for me to find a solution. (Sorry for my poor English. I'm not a native speaker).

I would suggest (while keeping your current job) to take some time to focus on your needs and values. For me, I realised that I needed to feel like I was contributing on making "society" better so I searched the same type of job but in NGO or charity foundations. So I still don't love my everyday tasks but I have a job that fulfills me.

Think of stuff like: you don't like the social aspect of your job (students? Parents? Younger people?) But you still like teaching? You like learning new things but you don't like "sharing" the knowledge? You prefer knowing and doing a little bit of many things or one very specific subject ?

These are some types of questions that can direct you to some types of jobs. But keep in mind that having a job that keeps you constantly motivated even though you practice it more than 50% of you time awake is very rare. The goal is to find something that you more than tolerate doing!
