Recalling 7th February

My mom has told me she has pain on her stomach. I googled her symptom and assumed that she might have a problem with hearts. I was worried so much. A friend of mine told me she would be alright, saying when she googles her symptom, she always have cancer. But why my bad feeling never goes wrong? My mom was diagnosed with heart failure in the end. On 7th February, I got this news, and I cried so much. I started and finished a day with tears everyday. It was the worst day ever in recent years.
