Fear Factor

Not sure since when, I fear going to work. I fear getting out of bed in the morning thinking of my work day and things to do, things to finish.
I begin to feel really meaningless to keep doing a job that I hate. I do not feel any sense of satisfaction. I do not feel any sense of belonging or any remote sense of this industry I am in. I feel...so out of place.
What has happened to me? I know I need money = that is why I worked. This is making me breathless. I am attempting to change a new job in a new industry. Alas, all my friends and even my family do not support me. I have to take a very very big pay cut. I have to be realistic. But really, the agony of going to work everyday is like.....a death sentance hanging by my head. The drift is real.
I do not want to end up a loony bin. I do not want my child to grow up without a mother. Please. My Fear Factor = going to work everyday. Now I have fainting spells in office. I get fast heart beat with total breathless at times. I get gastric upset that I never have before. I get running stomach when I am sure I did not eat anything wrong.
Help.........
