Its so hard to focus on anything but that and its causing me not to remember how to do my school work...

I think my grandma might pass away today...My dad said if she does; He'll come get me from school...I can't think about anything but that...I wish he'd just let me stay home today instead of coming to school...i can't stop the tears...I can't remember how to do any of my school work because my mind is else where and my head hurts and my mind isn't in a very good place to the point where i can't even function properly...Plus i didn't get much sleep last night..My mind wants all of the pain to stop but it won't...it can't...I need to find a way out of this...I can't keep on like this...
