I'm not really sure what to write here but in the moment of feeling hopeless I feel like I have to express something somewhere.

My grandmother brought me up as both my parents have passed, I'm 22 and currently I'm her full time carer. We found out at the start of the year that she has pelvic cancer which has spread through her uterus and other areas, and not long after discovered it was terminal. Just after having the doctors come in today as her symptoms are getting worse were told that it could be an end of life thing, and I'm not really sure how to feel. My chest hurts and I feel heartbroken. Not sure I have the emotional capability to handle what's to come and just want to know if anyone has been through the same.
