Mood swings

I'm having mood-swings these days. I don't know why but it is happening as a consequences of events, for quite unrelated reasons. I don't have to worry about my future as I've a backup of being engaged in my family business. Nor did my girlfriend dump me because I don't have one. My relation with my family has evolved over the time.
What is killing me from within is the fact that I don't know what's happening with me and what I want to do. More than 50 percent of the world's human population dreams of a lifestyle that I currently have (I'd have loved to write 'enjoying,' but am I really?).
What a writer dreams of is freedom, and when that is missing, it becomes difficult for him to make things work out. Mind you, I'm not talking about physical freedom. Many great souls have written magnum opuses in a prison or during house-arrests. Though freedom was denied to them but they had the freedom of mind, freedom of thought and freedom of expression. The problem with me (as I dare to speculate) is that I can't even express to myself. I don't know what I want to do? A much vexing, and rather controversial question is that why am I in this world? I won't indulge into the spiritual aspect of the origins of life. Maybe I'll save it for my next blog. Seeking the answer to the first question only would take me to the other side of the bridge.
Amidst so many things happening to me, I'm confused. For a quick recap who aren't familiar with me, I'm a graduate in economics from Delhi university with a first division. The purpose of writing first division is to disillusion you from the fact that it's a highly paid course. You can take my word for that. Entry level jobs won't pay you more than 13-15 thousand a months, barring those sensational news that blazoned the newspapers for paying 32 lacks package to 2 DU students last year. (I won't comment on how did they manage to get those as I don't have first-hand information).
Concentrating on my final year, I missed the opportunity to prepare for masters in economics. Here, I declare that it was entirely my mistake for not filling in forms of those colleges in which I'd have got on merit. As time passed by, my temperament nudged. I desperately needed to do something. So I took on what I had kept in mind to do after my masters because I thought that I already have a backup -- UPSC civil services exam. It isn't a cake walk, and I kept that in mind. Four months into honest preparations starting from mid-October, things were just too fine before I was struck with horrendous typhoid (read my previous article for a month through the disease).     As I write this article, I'm stuck in a dilemma -- to continue with UPSC and put on stake another year or to take up masters in a non-reputed course -- but why? I shouldn't  bother, technically. 
'The only need of humans is food, clothing and shelter; the reason people stock degrees is to have better food, better clothing and better shelter. With your knowledge you can be assured of the basic. Rest you should leave on the destiny AND take things as they come' -- As my teacher once said when I expressed my grief.
Its not only academically but on the emotional front too.
Having said that, the question remains unanswered 'What I want to do?'
