Having a ruff day my mom called me before to tell me my Nana isn't doing well. She has been in the hospital for days now but has taking a turn for the worst. I'm so upset can't stop crying this sucks so much. I am so close to her and she has been so excited for this baby. I can't even imagine what's going on in my dads head right now this is his mom. They are putting her on a morphine drip so she doesn't feel anything. How do I explain this to my son when we go see her later. He is 7 and knows about heaven and hell but still. My heart is broken 💔💔💔💔💔😔😢😔😢😔😢😔😢😔
