Is it possible to find contentment when you are grieving a loved one?  The answer for most of us would be a unanimous no!  We want our loved one here with us so that we do not have to live life without them.  We want things to be the way they always were. Since we all grieve differently, no one size fits all.  The word contentment by definition in the Merriam-Webster dictionary states- the quality or state of being contented; satisfaction, ease of mind.
The reality is, we do have to live life without our loved one. It may sound cliche, yet it holds true-take one day at a time. Putting one foot in front of the other.  Cry when you need to cry.  Pray for strength each day and know that some days may be better than others. Seek professional help if you are unable to cope with things.
Wholeheartedly, the one thing that has been very helpful for me is to find something each day to be grateful for. Writing in a journal is a great way to look back and read what I'm grateful for.
