You mention counselling, therapies and books - which all focus on your loss and how you feel about it. I'd aim for gains, instead.
Get involved in new things, like volunteering, group activities, learning, following interests and exploring. I studied for a degree to focus on something positive, rather than my grief. Grief is individual, goes through stages, takes a very long time - and there's no right or wrong way to do it. Look after yourself in the meantime!
