I'm so sorry. Living with sadness is so hard. You still have to get up every day and live when all you really want to do is stay in bed with the covers over your head. But we don't do that, do we?
It's OK to be sad and to morn the loss of love; allow yourself to do that for as long as you need. But don't forget to live. I read in a book once that "lovers will always find love." Very simple words, but I believe them. Those of us who want love will find it again. It took 17 years for me after my divorce but I found love again. I had terribly sad and lonely times in those years, so I relied on friends and family to make me push the covers off and get out of bed. Rely on the people around you to find yourself again.
Hopefully, your husband does the same and you will find yourselves re-building your marriage. In the meanwhile, the way you live your life has to be about you. That's not selfish, its how to survive.
ROCK ON........Trish
