I'm doing a startup and I've gone through some really rough times, like going for 5 days without sleep because of anxiety due to cashflow problems. My wife gave me sleeping pills (she's an M.D.) and was generally supportive. I didn't get professional help from a psy*. It passed in 2 weeks. I learned a lot from the experience and grew as a person. I have faced similar situations since and now can handle them without losing sleep.
I would recommend to take some time off and _travel_, ie. active vacationing. If you just sit around at home that's probably no good. Also, if you can't sleep, take some pills.
This may sound odd, but I found reading books from the Dalai Lama also helps to handle issues like this on an intellectual level, ie. remove the negative emotions and just figure out what's bothering you.
