It is indeed a difficult time for many,myself included.
Perhaps the thread 'Blue(Sad) Christmas(as opposed to Merry)' in the General Discussion, would provide some insight and let you know you're not alone. Others share the same feelings about the holidays.
Regardless of what your mind may say, deep down inside you, may you find you are not alone.
Grace and Peace to you my friend.
If need be, don't hesitate to call the crisis intervention line in your city, or go to the hospital. You need not suffer.
