Grief - delays?

[IllegalAlien]

2 years after my sister died and I've sort of suddenly realised she's dead.
I feel sick, weepy, scared, ill. Why now? Is this normal?

Yes, in short. Grief is horrible. I think it is almost like ptsd, in that you carry on your life, and then something happens and you relive the whole thing again. I was on holiday, for example, happy, not thinking about anything except enjoying myself, and suddenly a song that was chosen for my brothers funeral was played. For some time I was reliving the dark days of his death and just ended up in tears.
Don't be hard on yourself. It helps to talk to friends/family. I get great comfort from sharing memories of the deceased with other people who have known them (I have lost 3 members of my family in recent years). We often end up both crying and laughing. Personally, I don't think grief ever leaves you, but you learn to live with it. Don't try not to remember, spend time thinking about your sister, it hurts, but it helps, in that it stops being a dark place you are trying to avoid, and you learn to deal with the emotions that thinking about your loss brings.

It is so weird. You’d think the human brain would be able to wrap itself around the idea that someone is dead but I have found it takes years. I think it’s a protection mechanism, we couldn’t handle it all at once. I find it helps to think of it as the tide. It comes and goes.

Thanks Lucisky and Hermione for understanding. And I'm very sorry for your losses.
