Tonya: I agree with Denise, you might find solace in sharing something, a memory? your sorrow? with your niece. She is greiving too and you might find something to do with her, in memory of her father & your brother (buy a special gift for her mother? Plant a perennial for her dad? maybe start a place in your yard, a memorial, to family members?). There are ways of sharing grief that help soothe the emotions.

Rosie has a great idea too, a grief support group might be very helpful (and a few months is nothing in the grieving process!).

Finally, my dad died 10 years ago (at a ripe old age, so the grief was a bit less intense than for your young brother) and I still find myself wanting to talk to him, to get his advice, his 'take' on things that are happening. I don't think that will ever end. I think people we love deeply are always in our hearts & our memories. Your brother will always be in yours. - Candace
p.s. My brother (who now has a reoccurrance of his cancer) planted a memorial garden to his father-in-law. It has a bench and a sign that says "Gene's Bud-Light Beer Garden Memorial" or something like that. There is a bench and roses (or azalea? Don't remember). They sit out there once in a while & drink a beer to Gene. It is a nice, happy reminder of Gene.
