I have a "so called" job which pays me well. But i don't like it. what should I do ?

I have been meaning to post this for a long time.I'll make it short.

I have this job which pays me really good. Even if i don't work i get paid. But i don't like it from the beginning, i studied something different which was a passion but right now it turned to a money making job. The place i work sucks its just a lonely life and all 6 days i have to work. Its like am kind of stuck here. i want to move to different country but something stops me coz of my responsibility i have towards my family. it's like am not able to get out of my comfort zone. i don't know how long i can be like this. I don't know what to do.
