It is a tough situation to be in & I can relate. I also do not like my job but then who does? Anything which makes us little uncomfortable, which forces us to come out of our safe zone, we hate those things don’t we?

But I tell you what. Look at what this job is giving you. It is giving you a decent salary, a security that even if you are sick you will get paid and many more benefits. I know you don’t like it. But first accept the good things your job allows you to have.

Next I would suggest you to do 2 things:

1. Do some physical activity to destress and reduce the anxiety. Anxiety is all in our head. When you are putting such strong thoughts of hate & discomfort & your constant struggle to go abroad for travel it all kinds of keep your brain engaged for 24 hours. You need to vent out this excess energy otherwise it will come out in form of all symptoms you mentioned. I did same and trust me physical activity helps a lot to resolve these issues.
2. Make a plan that how you could switch your job? Make a plan how much money you would need to quit your job & travel? And then start executing those plans.

In short focus on positive and constructive aspects of your life. Try to minimize negativity. Focus on doing stuff rather than thinking about it.

Try these two things and do let us know if it helped.
