Troubled

I guess i have not really been myself lately.I am so troubled because of my grandmother.She is really critical and i am really worried.I have never seen her so sick and weak before.Those previous admissions to hospital,she can still talk healthily,but now,she can only nod her head to response.I have really witness how things can change within a snap of time by how things are going around me.It is really bad and scary.Lots of things are happening i really don know how to handle them.Can i do anything to change or help ? Please tell me
