Persistant anxiety & fear. Feel either!

Since last few months I have been facing persistant feeling of anxiety and fear , sometimes for no apparent reason. Many days I wake up feeling scared,as if I had been in a nightmare. I am going through a difficult phase in life. I hate my current job, but have no idea how to get out of it, I had to break up with my girlfriend of 6 years because her parents didn't approve of our  relationship ( partly because of my ethnicity and partly because of my job) . My parents feel I took a wrong decision in life by doing MBA instead of preparing for banks. Although I am not feeling suicidal, but while traveling on a bus/vehicle whenever I have a near miss on highway,a part of me secretly wishes that I die in an accident, so that all of this useless life of mine ends without all the mess a suicide could create. Please help me. I really feel hopeless. I tried talking to my friends, they think I am a very negative person, and my family, although they love me,  doesn't understand how I feel either
