I am totally confused about my career, help me out!

Really depends on what you want to do and in what filed. Commerce on it's own is HUGE.

So what interests do you have in this field, best to play to your strengths.

Commerce is just too broad a term. It covers every aspect of the business world of selling and buying. YOU tell US what you are interested in in life, and we will make suggestions. Knowing where the best jobs are is good too, but not nearly as important if you aren't happy in that field.
