I am so sorry for your loss. I had a sister who met a guy at 15, married at 21, he died when he was about 78. She was devastated. She had a stroke before that but could talk, she gave up trying to walk after he died. She cried all the time.
I'd suggest finding a support group in your area to go to. I went to 2 and a therapist when our daughter was killed, they DO work.
Again I'm so sorry, I'll tell you what stuck in my head at my daughters funeral from my Brother-In Law,
TAKE CARE OF YOUR SELF. It's 1 day at a time, at your pace, no one else's, do not let anyone rush you, it takes time.
