Tracy, Personally, I don’t think one can just “get over it” when it comes to losing a life partner. Everything we do has our partners included in our life and then they are not anymore. The way we deal with grief is usually how we learned it in childhood, sometimes early adulthood if we haven’t had to endure the loss of a loved one or seen our parents deal with one. Sometimes that comes to us with a break up, a loss of a beloved pet, perhaps the loss of a relative. For those here who have ruptured, it could be the loss of our perception of ourselves. The one thing that is constant is we have to learn to handle grief.
We all have to go through the different stages of grief, in no particular order. Exercising does help if you are able. Talking helps immensely. See if Hospice in your area has a free grief counseling service. If you’re able to return to work, that may help as well. Many people find relief in journaling. Some can find relief in a hobby or starting a new one. Joe recommended a book he read here Trying to control anxiety
