So very sorry for your loss of your wonderful Dad. No matter how expected his passing, it still leaves a huge gap, and it's quite natural to find things have blanked for a while.
I feel it's our own body/minds way of limiting what it allows us to cope with, as the passing and grief is something we can't prepare for.
Give yourself time, even a few hours can make such a difference, but please let yourself come-to just as you are able.
I won't say to try to sleep, I couldn't, but do please try to rest, tomorrow is another day to be faced. You have managed to get through up till now, and although different, you will manage tomorrow as well.
My heartfelt sympathy goes out to you, and any other family involved. Take care of yourself, and feel free to come to Talking Point whenever you're ready.
Love, Necion. x
