Long fasting while going to work

I wonder what the experience of fasting while working is like?

I feel that my body and soul call out to me to go on a long fast. I have been struggling with some health problems - lymphatic congestion, graying hair (I'm 31), mild back pain - and internally I feel I am very toxic.

Last year I did my first long fast - 7 days - and I was on a long leave from work then. Day 5 onward I did not have the energy to leave home, so if I had been working, I would have had to take a leave. This time, I have been following a high raw diet for many months, plus cleansing in other ways, so I am expecting to be able to fast longer, although I have also had some emotional stress which may have made me more toxic. So I will have to take some time off from work. Maybe a fortnight, or more.

Plus, I lost about 20 pounds last time, in the fast and also later on a raw food diet, and had a lot of comments about looking ill, too skinny, and so on. I would want to avoid that, especially when I am still on a fast, given how sensitive one becomes to other people's vibrations and statements.

So it seems that I cannot go on a long fast unless I take leave from work, which is unlikely before 2 months from now...

How do you fast for long days - 10 plus days, for example - while still working? Does anyone manage to do that?
