Sorry to hear that John, you must be feeling pretty stressed. Sing yourself a nice calming song or two - I know it won't help, but you'll feel better..
I work in mobile phone networks software, and business is pretty rickety in that area, but luckily I work for a very big company which can ride things out fairly well. Nothing to stop them getting rid of the mobile comms side of things though - so every so often we get a bit jittery......
I hope things pick up for you.
