Deaths in the family are never an easy task to overcome, much less, forget about. You ask "how can I forget," but you may never forget & that's ok & totally healthy. You're just juggling a lot & just know that other are also. I know that you're tired & feel like everything is going down the "shitter" for you, but continue to push through it, I promise it'll eventually get better. I'm not saying within a week or month. Give it some time. Be strong. I say this because many people result to doing drugs & even suicide if it gets to that point, but don't let it. If it gets worst, I would seek professional help. Hope that this helps a little as I know that I'm not in your situation, but I do have some knowledge on the subject. Cheers & remember, you're not alone.
