Tension as I'm 30, no job, WRITER'sCRAMP

I am 30 year old male and have done 5 year integrated B.Tech & MBA(Specialisation in Finance) course from a reputed college in Mumbai called Narsee Monjee Instt of Mgmt Srudies. My CGPA was not good - 2.7 out of 4. I took up a job in JM Financial Services New Delhi as Management Trainee in 2011 and quit after 8 months as I did not like the marketing type of job where you plead with wealthy clients to invest in certain portfolios. I found it demeaning. I did not get placement from my campus as my other classmates got. I got the above job on my uncle's recommendations. I felt bad because of this too in continuing with the job. Then I decided to write the UPSC Civil Services exam for IAS etc. I gave 4 attempts sitting at home after taking best of the coaching staff in Delhi . I cleared Preliminary exam all the 4 times. But could never clear the Mains written examination. I am suffering from WRITER's CRAMP due to which I can't write fast and my hand shakes and I become tense. I'm jobless
