M.G. visits your office requesting a consultation.  He explains that  he was caring for his elderly mother after being diagnosed with  dementia.  He reported he was her sole caregiver and struggled with  watching her deteriorate.  He expresses concern that he isn grieving  properly because he feels relief that she passed.  He recounts that as  her disease progressed, she became aggressive when she no longer  remembered who he was.  He tells you that during that time he prayed  often that he would behave differently if only she could show  improvement.  He also tells you that he was angry he had no help and was  sacrificing years of his life to care for her. 

Review the DSM-V and determine if there is an appropriate diagnosis for M.G., providing rationale.

Using a minimum of two scholarly sources, describe the stages of grief and if this patient is exhibiting abnormal grief.
