I can totally relate.

My wife and kids left to europe for 4 weeks to visit my wife's family. I am the only income on the house, and of course had to stay behind and work.

I also coped by working a ton of hours. I also went totally hypomanic. I slept an average of 4 hours/night, I averaged 60 hours/week while they were gone. One week I worked 80 hours, sliced my leg open, got 6 stitches and went to work the next day!
One night a raccoon was pestering my house and my cat, so I waited for him and jumped out the front door and stabbed him with a spear!
I also called an escort to my house. After 3 weeks of loneliness and mania, I also cheated with another woman...
Oh well, I knew my wife leaving would trigger a huge episode, I am just glad it was mania and not depression. I stayed medicated the whole time, which really helped me from being miserable and psychotic at least. But yeah, definitely had a REALLY FUN HYPOMANIA EPISODE!
