For a little backstory I(F18) have a step dad(44)with pancreatic cancer, he was diagnosed in may of 2024, he had surgeries and was considered NED(no evidence of disease) in April of 2025, my mom had concerns it would come back as most pancreatic cancers do. Tuesday they received a call saying a biopsy that had been done recently came back positive, now it is in the lung and on of the lymph nodes. They told my mom and my step dad it is incurable. They said the same thing about the one he beat in April of last year as well though, I have a positive feeling about it because he showed zero signs of it having been back, unlike when he first originally was diagnosed.

I have two little sisters who are 3 and 6, ever since being given a car my responsibilities have increased, I pick up my sister from elementary school, which isnt much of a problem other than she gets out 30 minutes before im scheduled for work nearly almost every day.

I sleep with my 3 year old sister and I have since June of 2024, when he was considered NED i expected them to start sleeping with her but excuses were given every time. "He wakes up in the middle of the night, the lights will wake her up" "He coughs loudly" ETC there were many more, I expected him at max they would sleep with her once I turned 18 because it is not my responsibility to sleep with a child when they are sick, waking up in the middle of the night, clingy, just a whole bunch of reasons. Nothing seemed to have changed.

I have a job, I am enrolled in college, I have plans for myself in the future. In the nicest possible way to my mom, I do not want to be stuck taking responsibility for children that are not mine, Our family is not active in our lives, We do not have a village. I am the village, when nobody can watch them it becomes down to me, when nobody can drop them off at school or get them ready, it becomes down to me.

After his recent diagnosis of it being deemed returned; my mom keeps having talks with me "Do you think everything will be okay? If not do you think we will survive?" When things get rough my mom has a habit of stepping away, she did it with me when her and my dad got divorced 10 years ago and was rarely around. Knowing this situation would be even more drastic and painful I know a majority of this will be put on me if the worst does take place in the future.

She does genuinely everything she is the most amazing mom you could ask for, but I do not want to be in the parent position down the line, AITA?
