I finally realized that there is a term for the situation I am in,"burned out". What can I do to recover from a short term burnout?

I am at the the last four months of my MSc program and I haven't started my thesis yet. The reason was complicated, the MSc program was quite different from the one I had in mind. So, from the start I felt I was wasting my time by continuing at the program. The only reason I didn't quit is because the scholarship is sponsored by the company I used to work. I am still their employee and I am expected to join them once I finished.

If I quit, I wouldn't get promotion not to mention the "he wasn't able to graduate" rumor. Besides, I am supposed to serve three years as a pay back for the scholarship they gave me.

Despite my adviser's genuine effort to help, I am not able to pull myself and do something. I continually failed to see my adviser despite having an appointment with him. The only thing that crossed my mind for months as a solution is SUICIDE. I am deeply stressed and have presumably stress initiated headache that lasts for weeks.

What would you do if you were in my position?
