How can i get a better job?

I quit my job in June. I used to work in an international trade campany as a foreign trade salesperson. Back then, it seemed that I had found a stable job like my parents had told me to, but I felt the job didn't suit me. I had to work overtime, so I felt really tired everyday. After a while, I quit, came back home and rested until now. During those days, I tried to find a new job through the internet and attended some interviews, but i did not choose any of these jobs. Sometimes i just feel I don't know what i really want and what my dream is?

I feel upset all the time and hope someone can help me escape from this trap.

<em>I might be wrong, but I feel "have a rest" is generally used for short periods of time, not long periods such as the one you are describing.  </em>
