Aww, don't worry about it. No should blame you or hate you for it, if they do they are heartless and don't deserve life(okay, maybe not that drastic). I hope your father gets well soon and you should worry more about your family than us here on Mibba. Family is always important regardless of the situation. Spend time with your father. Good luck.
That ok, I just hope that your father will get better and don't worry about your story. I think you spend this time with your dad. My best wishes to your family .
