Should I choose end of life care over my own life?

My only surviving parent is 80 years old and a dementia patient. A memory care home is expensive, very expensive. For the time being I am one of the primary care givers. My mother had a traumatic life, and sacrificed a lot to give us better futures.

I occasionally get the perception that my siblings are toxic for not considering us jointly hiring outside help or considering a memory care home. I have dreams, ambitions and romantic interests that have been on hold for too long and at 40 years old my time is running out.

The thing that irritates me is that my siblings see nothing wrong with this. For context I come from a culture where people care for their elders until death. No amount of expressing how unfair I believe the situation is gets their attention.

Am I selfish for feeling this way?
