What should I do? pls suggest

That depends upon you. If you need the money, be patient to stay where you presently are if you could not as yet find a job which gives you satisfaction with a very good income. If you are capable of living your life with a lesser income, then go to where you think you are satisfied. But I believe that it's very difficult to find satisfaction. It may seem that the job you are going to could give you satisfaction but there are realities in life that eventually lead you to say that you are not satisfied with that job. Evaluate the pros and cons very well, and if you could be patient to stay where you are, just stay there. There are so many people who are employed in fields other than their line or educational attainment.
