Dear Shital,
I do not agree with your comments that the job you joined is not the place for you. Will you keep on running from the realities throughout your life?
Accept that this is the job you needed most. You can do it. Relax, gather your strength, and work to achieve the targets set by yourself and not by others.
I remember someone I knew resigned from the post of junior teacher from a very reputable school. The principal asked her why she resigned if she had a better offer. She replied that she wanted to do something with her life, and the job as a junior teacher was not her destiny.
The principal replied, "Well, Miss, if you want to do something with your life, stick to one profession, and you will get what you want; otherwise, you will be lost in the mire."
And you know the principal was very right. She stuck to the teaching profession, and by the time she retired, she was among the top four principals in the country.
Please understand, you worked hard to achieve this job where others failed.
It is a matter of only three years. Once the mandatory period is complete, you will not only be at liberty to choose a better job but will have earned experience as well, and maybe you will find yourself satisfied with the progress.
Consider it as an apprenticeship that pays for your day-to-day needs and trains you as well.
Consider what I have tried to convey to you; you will not be sorry in your life. And the story is true.
