Am going through a life-threatening disease in the middle of a war-zone in Israel, alone without family, undergoing teeth extractions and a tumor on my parathyroid with kidney failure no less – need chizukim because am totally losing it

My faith is being shattered, have no one to discuss spiritual matters, have tried – repeatedly to no avail. Is this how it ends? Did I sign up for this since day one? Is there no assistance to be sent from shamayim to help me, us and everyone affected by these times? I am on the border of just wanting it to end. Really. What is the point. Made aliyah, did the whole give it your all and I am completely done. Done emotionally, done physically and done spiritually. I just can’t.
