First of all thank you so much if you've taken your time to read this piece. 
My mother is everything to me. She's the person I love the most in this planet, she raised me really good, always cared unconditionally after me and was an amazing mother. 
In this pandemic I decided to do my remote work closer to her and my father, so I moved in together.
However, over the course of the last days (about 2 weeks) she has shown an intense headache that completely disables her: she cannot work, cannot their daily things. It is a real abnormal pain. So we went to neurologist and he immediately recommended a MRI Scan, given her age and history of breast cancer. And now I find myself struggling to cope with such anxiety for the result, plus the fact that I have had to take care of her: take her to doctors, to do exams etc. To see her suffering like that really scares me of being something serious and I really can't see myself handling a bad diagnosis. Any advice or thoughts will be appreciated.
