Sometimes things in life change for the better. Sometimes you will not always stay a carer. The person you care for may grow up and live on their own, if they are elderly they may pass away, or you may discover your own path in life and move to a place thats better for you but make you unable to care for them anymore. For me i moved to a place that makes me happy and im now unfortunately unable to carry out my caring roles so somebody else is gonna have to take on the responsibilities that I had to, they will experience the stress I went through, its not a nice feeling but somebody is gonna have to take on that role. But sometimes things may change and you may take on those responsibilities again but with different people or even the same people but you may not always be a carer because times do change and you can't always put your life at a standstill just to dedicate your life to just that 1 person or people, you also need to look out for yourself.
