I don't know you, but I do know what it's like to lose someone you were close to, happened with my grandparents for me. Just know that you gotta ride the storm out, get out there and do stuff. That helped me, and eventually, I "got over it". I don't think people every truly "get over" losing a loved one, but they can certainly move on at the very least.
I'm not sure how much this advice will help you, after all different strokes for different folks and all that, but still. I wish you well.
