Turkish Airlines Refuses Economy Flight Reschedule Despite Storm Warning

I have a flight from Istanbul to Adiyaman on Sunday, March 26th, and another flight from Adiyaman to Istanbul on Monday, March 27th. However, due to the recent earthquake, I was forced to arrive in Istanbul earlier than expected. Now, because the weather in Adiyaman is bad and it's raining heavily, I wanted to cancel or reschedule my flight, but it's not possible because my ticket is in economy class. I am an earthquake victim who lost some relatives in the previous earthquake in Turkey. I had planned to visit their graves while I was here, but due to the storm and heavy rain warning, I had to cancel my plans. I'm hoping that the airline can assist me in either canceling or rescheduling my flight because visiting my relatives' graves is very important to me. I understand that these things happen, but it's very difficult for me to deal with this situation on my own, especially since the trauma of the previous earthquake is still fresh in my mind. I'm hoping the airline can assist me in finding a solution. I demand a free reschedule.
