Sounds like things are looking up for you in the horizon. You just need to hang in there.
One thing you can do that I think might help...the week you are off why don't you plan to take at the minimum of 1 hour per day and use that time to dream. No phone, no relatives, no e-mail and write down a list of things you are grateful for, a list of things you would love to have in your life and a plan on how you intend to accomplish them.
I would also suggest NOT watching the news or anything depressing. Lots of funny movies, modivation CD's (for lounging about the pool), wonderful books from inspiring authors.
Then when you go back to work, PLAN on at least 30 minutes each day and do the same thing.....read/update your grateful list, review your dreams and aspirations, read how you intend on getting these things accomplished.
Might I suggest, 1. I WILL find reliable help for those days that I need to leave.....
