Hitting a Road Block

I... had worked in the IT industry for coming to abt 7-8 years and finally decided to give up all those years of experience, hoping to have a change of environment and a new experience.

With the advise from a tarot card reader tht I went to once. Sales is where I will raise and shine, I decided to venture into sales and marketing.

Sales & Marketing is a totally new subject to me, and I know I have a lot to learn and pick up. However I am hitting a Road Block in my life again, I dislike going to work at my current coy. I hate working with tht bitch who have low EQ and shout at me when her mood is not good.

Is it the prob with my ego? I never like to be shouted at, for 1 thing I know, I am also in the management lvl, why do i have to still allow myself to be subjected to such treatment?

4 mths ago, when I decided to leave my comfort zone. I was prepared to go jobless for a while before I really settle on the job that I really wish for. 4 mths later, I know i have to leave this coy but why aren't I willing to take the leap?
What is it tht is stopping me? Many have say tht this will look bad on my CV but I really dun see any prospect working on.

BUT WHY AM I STILL HOLDING BACK??? I need a sign.. A sign to tell me shld I stay on or move on while I still can...
