Hi All,
Would like some advice on how to deal with grief that’s manifested?

You could try
The Grief Recovery Method - created in America by John W. James who lost his son in 1980s and says in his video that the help people offered was intellectual in nature he says his brain was not broken but his heart was. Carole Henderson was so impressed she brought the method to the uk after she lost her husband in about 2007.
It looks like it could be helpful. I am summoning up the courage to do it afterall it couldn’t make me feel worse than I already do.
