To see your best friend lose her husband can be heart wrenching. After all, one can only imagine the feelings that come after your soul mate has left your life. That being said, you'll likely feel compelled to assist your friend in any way you can during her time of need.
However, she might not want you to be there for her as she goes through the mourning process. Everyone deals with grief in a different way, and your friend might want some space immediately following the death. In this instance, HelpGuide.org recommends simply letting her know that you'll be there for her when she's ready to talk.
The Harvard Medical School also encourages you to shed positive light on the situation as your friend goes through this difficult period. Being optimistic and offering hope can help her during the grieving process.
Finally, consider contacting a psychic line if you're worried about how your friend is handling the death of her spouse. Authentic psychic readings can let you know if and when she will come to terms with the situation. In the end, you'll be able to gain peace of mind.
