Processing Grief

The response I read here to many comments about loss is ‘you haven’t processed the grief” . I haven’t read HOW to do that using the model. Can you give an example of the C= the loss of a parent T=I miss them very much F=lost, sad, lonely A=eat to buffer R=gain weight, miss parent more . HELP for a NEW way of processing grief using the model WITHOUT changing the T of missing them very much
