Hi @La77, I’m so sorry to hear about the loss of your dad. I hope you find our community helpful.
I think the question of going back to work is a really personal one - some people find having something to take their mind off things helps, others feel that putting on a, “brave face” can make them feel worse. There’s a thread here about going back to work which might be helpful to have a read of: Returning to work after bereavement
Take care
