Being sad is really hard. Holidays can be even harder. I have spent some holidays alone...particularly my first Christmas after the loss of my first husband. Thanksgiving hadn't gone well...nobody seemed to understand that my husband had died 2 months earlier and they just went on like nothing was wrong.
Christmas can be just another day if that is any easier. Read a book, watch a movie, get Chinese take-out. If being around friends and family is helpful - then do that, of course.
I managed to find happiness again after the loss of my first husband, but have struggled more since losing my second husband. I know many people who have found different ways to be happy after being widowed, and I continue to hold onto hope that I will find satisfaction again in my personal life and another wonderful relationship, too. I don't know what you want for yourself, but in between the low points, I hope you can envision good things happening for yourself again. It isn't the life we wanted, but it is the life we have right now. I hate being miserable, so I have to believe that I will find a way out of the darkness.
Hugs to you,
Maureen
