❤️ to all those experiencing grief, and loss
OP, I was much like you when my DF died 5 years ago. He had a long term, complicated illness. But his death was sudden over a period of a few weeks, starting while we were away on holidays together. It was really traumatic, he was in huge amounts of pain till very close to the end which was just awful.
There definitely was some relief at the point of death - that his suffering, and our witness to it, was over. One of my siblings made it back from the other side of the world with only a couple of hours to spare, so we were also relieved he was there.
I was back at work after a week (Ireland, so funeral was two days after he died). I didn't really cry, I still haven't (I would usually cry a lot). I felt nothing at all for months.
Then I did start to feel grief; I don't think I've really dealt with it (and as a family, none of us have).
I do find I miss intensely the man he was before his illness, and how he & my mum interacted (and counteracted) each other. She's become very difficult since he died.
It's strange, grief. Not only are there no rules, there's no understanding how we might individually feel and when.
I have an excellent counsellor for other matters. I don't talk to her about my dad but I think the other matters we cover probably tap into some of what I'm feeling.
I wouldn't necessarily rush to counselling yet - it's too soon. Give yourself some time first of all.
