I'm so sorry to hear about your current situation and fasting can only be making it more difficult. I know how draining it can be to be in a job you hate. it's part of the reason I'm not working right now because I basically had a nervous break down a few months ago, due in large part to my job. Also, during my fast I've had a few really depressing days and I think that is probably part of the fasting process.
As others have suggested, maybe you should switch to juice or maybe break the fast all-together until you are in a better situation. You have done so well and the number of days is just arbitrary. You can always take up fasting again.
