I am so stressed, thinking about my father. I can't sleep at night because I'm constantly thinking about him and wondering where he is. It still feels so surreal, and I constantly keep reminding myself of the events that happend at the time of his passing until the the day we buried him. I am constantly having flashbacks of his funeral service as well as him being buried. I often just think of him laying in his grave, eventhough I know it's not him. What should I do to stop feeling this way?…
