Shock rocker Marilyn Manson was so upset over his 2008 split from Evan Rachel Wood, he refused to leave his house for three months.
Manson spent both Christmas and his birthday in January behind closed doors, and ignored phone calls from family and friends following the break-up last year (08).
The singer, previously married to burlesque dancer Dita Von Teese, says, "I spent Thanksgiving, Christmas, New Year's Eve and then my birthday entirely alone, except for (my cat) Lily. Everyone was calling me because it was the holidays. But I didn't even speak to my parents.
"It became a real period that I felt I had to go through - like something in the Bible when they go out into the wilderness and fast.
"So I started writing to address what I was going through at the time. That was mostly my relationship. I don't think it helped! It's not like any of this is really a good thing."
Manson and Wood have since revived their romance.
