Maybe you have had enough for now. I find that I have to do my browsing of certain forumes in small amounts. That's okey, though.
Are you talking to someone about this? I find that a T can help you work through some this.
My grandma died which brought up a large ball of guilt to do with my great aunt's death. Talking to a T helped me to reduce the size of the guilt ball.
As for getting on with it, we all greive at our own pace. Well, I better go because I think I am getting ready my daily cry.
I hope you feel better soon.
